Power BI analysis services connector - the remote server returned an error (403)

Hi all, does any one have any suggestions what to try to identify the configuration problem I have?
I have, a SSAS 2012 tabular instance with SP2, there is a database on the instance with a read role with everyone assigned permissions.
When configuring the Power BI analysis services connector, at the point where you enter Friendly Name, Description and Friendly error message, when you click next I receive the error "The remote server returned an error (403)."
I've tested connecting to the database from Excel on a desktop and connect fine.
I don't use a "onmicrosoft" account so don't have that problem to deal with.
We use Power BI Pro with our Office 365. As far as I can tell that part is working ok as I pass that stage of the configuration with a message saying connected to Power BI.
The connector is installed on the same server as tabular services, its a Win2012 Standard server. The tabular instance is running a domain account that is the admin account for the instance (this is a dev environment) that account is what I've used in the
connector configuration. It's also a local admin account. There is no gateway installed on the server.
Any help would be greatly appreciated, thanks, Brian

Brian-
One other common issue I've seen is the UPN not quite matching. Log onto the SSAS server as the user who's logged into Power BI. Then open a command prompt and run:
whoami /upn
Hopefully the UPN it says will match your EffectiveUserName test and will match exactly how you're signing into the Power BI site.
If that doesn't work, your best bet is to go to
http://support.powerbi.com/ and click Contact Support and describe this situation and someone from the Power BI support team should get in touch with you to troubleshoot.

PowerBI Analysis Services Connector Error 403

Hi all,
I have a problem with the configuration of PowerBI Analysis Services Connector. I fill all fileds but i have an error in the last step.
Error description: "The remote server forward an error: Forbidden (403)"
I don't understand this error because:
- SSAS acces are granted for my domain\user
- Office 365 account is the same user
- SSAS tabular model is granted for this same domain\user
Who can help me ?
Thanks

Can't connect to BI Analysis Services Connector

Hi all,
I had tried to connect with BI Analysis Services Connector. I had done all steps, but when I tried to connect with BI Analysis Services Connector, can't view cubes and appear a error message. This don't have specifications.

I don't undertand what is the error.
Please Help me
Thanks!

Thanks for your reply.
The error I got in the OC4J window is : WARNING java.net.ConnectException: Connection refused: connect
However, I have now been able to login to BI Publisher as Administrator. What I did was uninstall the full OBIEE (Basic) installation, and instead installed the BI Publisher component only, (along with OC4J).
Works fine now, although I don't know why it didn't work with the full install. Any ideas?
Cheers,
Stephen

Content-Type is net being set in HTTP header. Server returns 400 Bad Request error.

Hi,
I am trying to access an XML WebService. This service requires the content type of the request to be set to "text/xml". As you can see in the source code, I am setting the req.ContentType property to "text/xml".
However, this content type seems not to be added to the HTTP headers. The server returns a 400 Bad Request error as can be seen in the log.
I've attached a System.Net.trace log and it states:

HTTP 400 Bad Request error in master/detail report

Using APEX 3.2
I have master/detail report and thought all was working fine because the detail lines were less than 100. I increased the number of lines to 300 and then when the Save or Delete buttons are pressed, we get the HTTP 400 Bad Request error. I decreased the lines to 100 (about 32K) and everything works again.
Is there a size limitation on the detail? FYI - the header regeion is on the same page as the detail. If there is a size limitation, is there a way to increase this?
If you experts don't think the error is a result of the size, could there be another cause?
THANKS FOR YOUR HELP!
Sandie

Hi All,
Issue resolved:) ...that due to When calling a URL in the REST Receiver Channel, all GET variables are ignored
so we had to upgrade SP10 patch level 5 and all services are working as we expected.
Also pls check Note :2114322

Connection issue for Power BI Analysis Services Connector

Hi,
I have a problem with the connection to power bi.
the analysis services connector was installed correctly and I see in my account of power bi the tabular server, but, when wanting to deploy
database it marks me the following error: IMDExternalConnection
the user that I set as administrator has permissions on the server tabular connector.
An example :
register my account with this email from my work : [email protected], and the domain user is [email protected]
could you guide me to know why this mistake is happening?
what credentials does power bi use to access my tabular server ?
Greetings!

Hi,
Can you please share a screenshot of the error message? Is it during the installation/configuration of the connector?
If yes, I suspect it is due to invalid credentials. You need to use your windows account of the Analysis Services server admin.
If the error is during connecting to AS server from Power BI, most likely it is due to a effective user name mismatch. The 6th FAQ listed in this blog post talks about the IMDExternal connection error -

HTTP 400 Bad Request Error

Application Express 3.1.1.00.09
We have some users who are experiencing what appears to be a browser problem in one of our APEX applications.
When clicking on any button that does an insert or update to the database some users get an HTTP-400 Bad Request error message. The database does not get updated and anything they click on after that shows that message. In most cases we have been able to restore the user’s browser to the default settings and the issue is resolved. However, we were not able to isolate which browser setting is causing the issue. We have seen the issue in IE 6, IE 7 and IE 8.
Here’s the error we see in the Apache server error log (minus the date time stamp and IP addresses):
mod_plsql: /pls/ax_tastest/wwv_flow.accept HTTP-400 Invalid name
Does anyone else have a solution for this? Know what's causing it?

HTTP 400 Bad Request Error from APEX 3.1.1.00.09.
We were able to determine that only PCs which had the Google toolbar installed were getting the HTTP 400 Bad Request Error from a particular page in one of our applications. Further testing revealed that turning off the ‘auto-fill’ feature of the Google toolbar would prevent the error from occurring and the application would behave normally. We were able to identify a specific item on the page that was the root cause. The item was using the type “Text area with HTML Editor” which has been deprecated. We changed the page item type to “HTML editor standard” and this has resolved the issue with or without the Google Toolbar and auto-fill feature enabled.
Summary:
•     Browser setting: Google toolbar enabled with auto-fill enabled.
Apex page item of type: ‘Text area with HTML Editor’.
When a user clicks on a button in the page, that executes a page process, it results in HTTP 400 error.
•     Browser setting: Google toolbar enabled with auto-fill disabled.
Apex page item of type: ‘Text area with HTML Editor’.
When a user clicks on a button in the page, everything goes through correctly and there is no error.
•     Browser setting: Google toolbar enabled with auto-fill disabled or enabled.
Apex page item of type: ‘HTML Editor Standard’.
When a user clicks on a button in the page, everything goes through correctly and there is no error.

Axis adapter : Bad Request error

Hi,
I have a File to SOAP scenario (PI 7.0) where I am using AXIS adapter in the receiver SOAP adapter for NTLM authorisation. In the xml that I am trying to post, i have characters like & because of which I am getting a Bad Request error. Is there a way to resolve this? thanks!

Will the Power BI Analysis Services Connector work if AD and AAD UPN suffixes don't match?

We are using Azure Active Directory, AD FS, and DirSync with
Alternate Login IDs, which means that our on-prem usernames have a different UPN suffix from our AAD usernames.
Will the Power BI Analysis Services Connector work in this setup? Or do the AD and AAD UPN suffixes absolutely have to match?

Hey Adam,
From SSAS, we simply query AD by passing the UPN we receive from AAD. As long as AD can find a match, it'll work.
So if there is a way in AD to map a particular UPN to another value, it'll work.
For example: For a user A, her on premises UPN is
'[email protected]' but she uses '[email protected]' as her email address. From AAD we'll receive
'[email protected]' & since AD knows that this is same as
'[email protected]' effective user name will work.
Hope this clarifies! let me know if you have more questions.

Repeated "Bad Request" errors after clearing cache, cookies, and cookies.sqlite

I get repeated "Bad Request" errors when submitting forms, logging in/out of sites, etc. I get this on a wide variety of sites. I have tried repeatedly clearing all cache and cookies. And I just tried disabling all my add-ons (only have 4) and then deleting the cookies.sqlite file and this still made no difference.
I am using Mac OS 10.5.8 and Firefox 5.0.1 but I have been experiencing this problem in past versions as well, maybe as far back as the latest firefox 3. My main motivation for upgrading Firefox multiple times was hoping this problem was corrected. It never used to happen, it just started happening all of a sudden. It has never occurred on Safari and I am still able to get any site that doesn't work properly to work on Safari without any problem.
I experience this on many sites. One reliable cause of it is logging out of Facebook.

You did delete all cookies.* files ?
If clearing the cookies doesn't help then it is possible that the file cookies.sqlite that stores the cookies is corrupted.
Rename (or delete) cookies.sqlite (cookies.sqlite.old) and delete cookies.sqlite-journal and cookies.txt, if they exist, in the Firefox Profile Folder in case the file cookies.sqlite got corrupted.

Create a new profile as a test to check if your current profile is causing the problems.
See Basic Troubleshooting: Make a new profile:

If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)

HTTP Error Code 400 Bad Request error when connecting to SQL db

I realized I should move this to a new post since it was a new question...
I am trying to connect to a distributed SQL database from CS4.
Let me show you how the connection is built... and then maybe someone can tell me what I am doing wrong...
First I go to the database panel:
I click on the '+' sign to add an MS SQL Server Connection:
That brings up the SQL Server Connection window where I am supposed to replace the placeholders with my server values:
After I enter the correct values and click test, I get the error (HTTP Error Code 400 Bad Request)... These values work from SQL Server Management Studio on the same PC.
Just as a side note... I tried one other thing that makes me think SOMETHING is wrong here:
If I choose as OLE DB Connection instead... and click the 'Build...' button and then enter the values in the Data Link Properties Window (OLE DB Provider for SQL Server, and then the connection info on the Connection tab) and then click Test Connection on the Data Link Properties window, it says my test succeeded. Then I click 'ok' which takes me back to the OLE DB Connection windows with the connection string pre-filled, and click test on THAT window and I get the same HTTP Error Code 400 Bad Request error...
Hopefully that is enough detail that someone can can tell me what I have broken?
Thanks,
Mike

Why can't I access my Blogger account and publish a blog? I get 'Bad Request Error 400" when I try.

When I tried this morning to publish my latest blog post the message 'Bad Request Error 400' came up on the screen. It seems other bloggers have been having the same problem today. I have subsequently tried to access my google blogger account through firefox but each time I do so the same message appears 'Bad Request Error 400'. What if anything do I need to do about it? Is the problem your end or is it a google problem?

I was re-decorating my blogger .. then I got the 'Bad Request Error 400' .. I re-formatted my computer, reloaded all .. I can now access my Blogger sites .. Don't know what the problem is/was, but I solved it by reloading my computer to Out-of-Box condition, and all is perfect now .. I have an alert set up for this Error 400 .. Masses of people are having problems daily ..

Since Firefox updated yesterday I cannot post on my blog - getting 'bad request error 400' message.

When I opened my blog today (more than once) the page came up but after I signed in I got a page up which says 'Bad request error 400' and I am unable to create a message or anything else. When I go back to the blog page there are no options on the top right for new post etc. This was all after Firefox automatically updated.
