Project Server 2013 - "An unknown error has occured"

Hi !
Whenever I navigate to Project Center in Project Server 2013 the credentials window pops-up continuously even after entering correct admin account and after several clicks on OK button in credential window it says "An unknown error has occurred".
This is happening at every links. Even at Resources, Tasks, Reports, etc.. Is this Project Server 2013 stable or still has bugs in it.
I recently installed March 2013 hotfix for Project Server but still no luck. In ULS or Event Viewer I didn't got any
relevant exceptions.
I am even unable to connect to Project Server from Project Professional.
Thanks & Regards.

"An unknown error has occurred" usually means that the browser cannot resolve some data or something is missing. This can be caused by many issues. One for instance is deleting projects, but timesheets are still referencing it. Many others. This
is one of the harder issues to resolve, because often you don't find anything in the ULS.
Seeing that this error is occurring everywhere on PWA, I would first try rerunning the "SharePoint Product Configuration Wizard". If this fails at any place, that will be the first thing to fix.

Approvals on Project Server 2013 - An unknown error has occurred

Migrated Project server 2010 to Project server 2013. All the quick launch pages were working after I completed the migration. Started the process of publishing projects and statusing/timesheets to update project.
Now I see "An Unknown Error has occurred".   Tried all my solutions for Project Server 2010 without success.
Event log looks clean.
Has anybody seen and resolved this issue?
Cheers!

We are having the same error with an on-premise install of Project Server 2013. This is the error from the ULS logs.

An Unknown Error Has Occurred - Project Server 2010 - Tasks Page

Greetings!   Some of my resources are recieving the error "An Unknown Error has occurred" (in red) when trying to access their TASKS Page in Project Server 2010.
I've researched this error quite a bit and am finding suggestions and answers pretty much all over the board.    Before I have my server people start installing a slew of hot fixes - I want to know if anyone has an idea of the underlying cause
for this error.    Since this issue doesn't affect everyone (i.e. I can access my task page), is it possibly related to the actual schedule in which they have assignments?
Any help is appreciated.
Thanks!
~Randy

i have found the solution for this issue, you need to do this:
in the logs you must search the "exception" and the logs give you a ID, this ID is about the task assignment in the specific resource , so this assignment is corrupt.
this ID, you need to merge in the SQL server in the project server database, you need to merge ID task with ID Project with ID Resource, so when you identify the ID project and ID resource you can
DELETE this assignment in the project from project profesional, because this task has a corrupt assignment, you must delete
ONLY FROM project professional.
This solutión solve this specific problem for this assignment that

"An unknown error" has occurred in status report in project server 2013

Hi,
It would help if you could provide the ULS logs for this error, even the PWA queue error message. Then has it already been working before?
Hope this helps,

Getting "Unknown Error has Occurred" After Project Server 2013 DB Restore

Hi All,
I have restored our content and pwa databases as per Microsoft's guide, one Project Web App works fine and the other has the error "An Unknown Error has Occurred" on the projects view and also when viewing Enterprise Project Types.
Another thing I have noticed is that only the Sys Admin has access to the project sites even though users have been added as admins etc.
We are patched to the December 2013 CU / Hotfix and I have also run the provided service scripts by Microsoft to go with the hotfix.
Any help on this would be greatly appreciated as we are looking to test SP1 and apply to our production environment.
Thanks in advance...

PowerShell has a command called. Test-SPContentDB.
Run the TEST-SPContentDB powershell command on database and see if it provides additional information.

I have searched the internet but most similar issues revolve around the resource center. I did find one person who just backed up the databases and provisioned a new site with success, but this has not worked. I am using the farm admin account, but all users
get this issue.
Any one got any ideas?

Anyone seen this? If I delete this project the project center loads. Obvisouly I don't want to do that though!

Project Server 2010 Task page - An unknown error has occurred

Hi All,
I have searched inside the forum for similar problems but i didn't find any solution.
We have Project Server 2010 with December CU installed and
we are
experiencing
a serious
problem with two enterprise resources.
They can login to pwa succesfully but when they enter in the Task page the following error is raised:
An unknown error has occurred
There are no errors reported in the event viewer while in the ULS Log I found only this entry but i don't know if it's related with this issue:
Detected use of SPRequest for previously closed SPWeb object. Please close SPWeb objects when you are done with all objects obtained from them, but not before. Stack trace:

It's not a task related errors because i have alredy done an analysis of the resorce's assignments.
I have also verified IIS authentication settings as described in this
post but all had been alredy correctly configured.
We have a farm installation with two physical server:
Application Server with Windows 2008 R2, SharePoint 2010 Enterprise, Project Server 2010
Database Server with Windows 2008 R2 and SQL Server 2008 SP2
Any help would be greatly appreciated!
Thanks in advance.

Hi,
I faced exactly the same problem: some resources try to connect to My Tasks, and get an Unknown error. No error message in ULS or Eventlog.
I hope I solved the problem, and want to share the experience here.
First, by reading this article,
http://www.projectserverexperts.com/ProjectServerFAQKnowledgeBase/Unknown%20Error%20My%20Tasks%20Page.aspx: even if the SQL Query returns me no records, it gives me the idea to delete (unpublish) some tasks (i managed to identify some tasks which raised
the problem, by assigning a test account on them, and see that the pb happened).
So I decided to delete my project from the Published Database (and keep it in the Draft of course). Than in Project Pro, I opened and Published: the problem seem to be solved.
I don't know the root cause of the pb: maybe some SQL data were corrupted for an unknown reason.
Hope it could help some one ! Don't hesitate to give feedback if you solved this pb with this solution, or workaround.

MS Project 2010 - An unknown error has occurred while syncing to a SharePoint site.

Dear all,
I encountered a generic error when using MS Project 2010 to sync with our SharePoint 2013 on-premise. I want to clarify is it default behaviour or a bug.
When I start MS Project 2010 professional from new -> sync to Sharepoint by type in URL and the list name. I can create a new project list successfully. I have verified the tasks are sync to the Sharepoint and I am able to see them listed on site.
After sync, I save the Ms Project document to local computer. Named test1.mpp. Then I close MS Project. Then open test1.mpp again and then sync immediately. This time an error show up:
An unknown error has occurred while syncing to a SharePoint site. Ensure the SharePoint site is running and try again
Since I didn't add anything to the mpp file, I believe it doesn't contain any invalid data blocking the sync. What would be the problem? Thanks.
Mark

No, I didn't. I just fill the site path like:
http://sharepoint.com/sites/Project/
and then the List field:
ProjectA
I want to clarify the sequence should be:
After sync, I save the Ms Project document to local computer. Named test1.mpp. Then I close MS Project. Then open test1.mpp again and then sync immediately. Then error occur.

Try one by one i think 1 one will help you for sure
1.Try updating the published database stats, well do all four Project Server databases using this command against each database
EXEC SP_updatestats
query will take time to execute depends on data.
2. see the
link
3. These types of errors are likely caused by one of the following:
Corruption in the project data being viewed
Basic corruption in the view configuration.
For #1 this can be a custom field value that is filtered where one project has an invalid (null?) value for the field in question, so often just removing any filters configured on the view will fix this.
If you identify the filter in question then see the tips above about republishing (or possibly re-saving AND re-publishing) some or all projects to correct the data.
For #2 there are few options other than to recreate the view, copying the current view sometimes helps but not reliably.

Error:unknown error has occured;server returned http response code :500

Hi,
   I deployed one custom action block on 12.0 server.
   It creates a pdf doc and saves it under c:\sample on MII server.
   But when I run the action block in a trax, an error was logged: unknown error has occurred; server returned http response code :500 <server URL>
Need immediate help on this.
Thanks

Does the failure occur within the action, and if so can you identify where? It is always a good idea to put some logging at the debug level in your actions to help identify exactly where a failure is occuring.

I am trying to download an app on my iphone and when it asks me to sign in to my account i get a message "Could not sign in. An unknown error has occurred." Do any of you know what is wrong?

I am trying to download an app from Itunes on my Iphone and i keep getting a message saying " Could not sign in. An Unknown error has occurred." Does anyone know why i'm getting this message? I have had the same password for years so that is not why...

The RC helicopter's directions say its available in the App store for Apple and here it is in the iTunes store:
https://itunes.apple.com/us/app/icess/id558793179?mt=8 (released on 6/19/2013)
How do I get this to show up on my iPad and/or iPod touch app stores so I can then download and install it as needed?

HT5287 Anyone else getting "An unknown error has occurred" signing in to App Store?

Hi all,
I have just acquired a Macbook Air for my wife and after a few bumps, have it up and running except that we simply cannot sign in to the App Store. It's definitely not a userid / password issue (validated via login to app store from iPad/iPhone and set up new apple ID for the wife).
What is happening is simply: when trying to SIGN IN to App Store, I get the error "An unknown error has occurred". Spent 90 minutes on phone with apple support with no luck. I know there have been some server issues due to heavy load with Mountain Lion being so popular but I know folks who have managed to get in to the App Store from their Mac in the time frame I've been 100% unable to.
Any one out there with experience on this? (I've looked at the various threads similar to this but didn't find anything that seemed to help)
Thanks all

Solution... I formatted mt HD and reinstalled then applied updates. Something must have been corrupted in initial setup

There was a problem downloading ... An unknown error has occured -42018...

Dear all,
After upgrading to i-tunes 7 I'm not able anymore to download music. If I run diagnostics everything seems fine.

However downloading the songs I bought doesn't work.
Following error:
"There was a problem downloading "...". An unknown error has occured (-42018). Please check that the connection to the network is active and try again."
But my network is active and the diagnostics turn out OK. Please help me out!! I have songs to be downloaded that I have already payed for.

This didn't work for me, but to any who may be interested, I also was experiencing unknown error -42018 when attempting to download purchased music. Additionally, I was stuck in an endless authorization loop when attempting to play previously purchaed music. All this started when I installed the latest iTunes software 7.0.2. But I managed to fix the problem on my machine.
I run windows XP Pro, and unlike the majority of users I actually set it up correctly with a dedicated administrator account, and regular user accounts instead of just running as admin all the time. For me, that was the cause of the problem.
The new version of iTunes software required FULL CONTROL privilages on the iTunes and iPod install directories for all user accounts that were using the program. (Previous versions worked fine, so this is a new thing.) Once I provided those permissions, iTunes worked correctly. Follow this link: http://support.microsoft.com/kb/304040 for information on how to provide FULL CONTROL to every user account.
I hope you all find this helpful in solving your problem.
Good Luck,
Bill
