Portlet can not be contact

Hello,
System spec:
Portal 904
db 9.0.1.5
notbook memory: 1G
The problem:
We have a problem with one of our Portal 904 portlet.
After registering 2 Web providers, one to create a graph and one an outlook portlet on a notebook. we test them in our office, and all was well.
When we went to one of our customers, we tried to demonstrates the site with these 2 portlets, but instead we got: Portlet can not be contact.
We thought it was a memory problem or different java jvm but we are not sure, and can not test it now.
What can be the problem ?
Thanks

o Have you successfully accessed the provider test page (running on the laptop)?
o Did the provider registration go well?
o Can you ping the laptop from the Portal middle tier host?
o Have you tried replacing the laptop host name with its IP address?
o Have you checked the application.log file for additional information?

Portlet could not be contacted

Hello!
Has anybody experinced this problem:
we have the following:
Server A, Windows 2000,2GB RAM, 9ias(9.0.2.0.0) [ infrastrcture, Portal, J2ee container, webcashe ]
Server B, Database Oracle 9i
when accessing a portal page through Webcashe over SSL, the user receives the error message, "Portlet could not be contacted".
when accessing a portal page directly (not over SSL and not through WEBChache), results no error message.
The problem appeared when the tried to deploy an j2ee applications to OC4j,deployment failed and they rebooted the server.
http event_log contains the following error:

This is a synchronous problem between dcm proccesses.
You can solve it by installing 2591631 patch.
Also You should install 9.0.2.1 CorePatch before 2591631 patch.
And i want to tell that I think it isnt relevant about your problem "Portlet could not be contacted".
Good luck.

One click on the refresh button shows the portlets.
What can I do to avoid that?
I've also created a URL-Item in a content area-folder, that allows you to go to the specified URL (open in a new browser) by clicking on the URL-associated image; but as it works perfectly when I'm logged on, once again, I can't view the portlet as a public user, even when I refresh the page.
Do you have advice for me?

Can not transfer contacts from Nokia 1020 Windows ...

Can not transfer contacts from Nokia 1020 Windows Phone to Mercedes C.

Error 1638 - iPhone software update server can not be contacted.

Hi,
I can't update my iPhone iOS to 4.3.3 with iTunes since a few months i still have the 4.3 version. I am using iTunes with an iMac with all software updated.
I am getting the error "iPhone software update server can not be contacted..."
I made a few research and tried the following fix:
http://support.apple.com/kb/TS1275 for error 1638 > 1004
http://support.apple.com/kb/TS3297 with no success (specifically the Blocked by configuration section - 2 Rebuild network information, the hosts file under /private/etc/hosts had no information that needed to be commented with #)
After all troubleshooting I re-installed iTunes with http://support.apple.com/kb/ht1224
And I am still getting the same error...
What can I do?
Thanks for your help

Same issue still with OS X Lion, last version of iTunes, can't update to iOS 4.3.5 or restore my iPhone 4. iPhone isn't Jailbrake. I am allways getting the error: "the iPhone "****" cannot be updated at this time because the iPhone software update server could not be contacted or is temporarily unavailable." (error 1638).
I'd like to update iOS or restore my iPhone if needed but this doesn't seem to work neither as the problem is related to the conenction to the server.
Can anyone help?

I strongly recommend upgrading to the 3.0.9 release (iAS
1.0.2.2) with the 3.0.9.8.2 patch (this patch should be
available for NT/2000 this week). Also, the database should be
running 8.1.7.1 (or later), as explained in the iAS release
notes.

Jerry

Portlets can not be seen by Public Users: Help Please!

Hi,
I have seen another message that might be the same that is happening to me. I have created a content area, with folders and items. I have selected all available options to make them public , appart from publish them as portlets. I have added them to a page but when I enter the page as a Public User (without logging into Portal) the portlets can not be seen...There are others that can be seen ...Could you help me with this?
Many thanks
Mariela

I assume you're using the generic folder portlet to view the folders.
If you publish a folder as a portlet, are you able to see it?

Cannot access page groups via Navigator "portlet could not be contacted"

This is happening for 2 users. I see it the error in 1 browser, but not in another (logged on in both browser as same user).

What is confusing is how 1 browser gets the error but another does not.
Any suggestions?
TIA

This issue seems to be related to the specific URL used to access the Navigator. I was using a specific URL to display a particular page region for editing, namely
/portal/page?_pageid=6,3,6_23&_dad=portal&_schema=PORTAL&p_otype=FOLDER&p_octx=FOLDER.334478_1453&p_domain=wwc&p_sub_domain=SITEEXP
Once the Navigator is accessed via this URL, all subsequent attempts to access Page Groups Navigator portlet fail.
I changed my process to not use the URL above.

Patch 2744619 causes portlet could not be contacted

Hello,
Any anyone installed the Portlet patch 2744619 in an HTTPS configuration?
The patch successfully installs, no errors in the install log or portal.log. But when I log into Portal, ALL
Portlets have this error message:
The Portlet Could Not Be Contacted.
I don't receive this error message when applying the patch to a non-SSL installation.
Thanks,
- Carl

Found out to apply the patch to an SSL enabled environment you first must disable SSL, apply the patch and then enable SSL.
If you are running UNIX be sure to set PTLASST.CSH to execute privs. During the upgrade, this file is missing execute priv so when configuring SSL, it will fail.
- Carl

Pls/portal shows: Error: The portlet could not be contacted after SSL enab

The OCS /pls/portal page shows: Error: The portlet could not be contacted, I believe this happened after SSL enabling the system. Anyone out there seen this errof before?

FYI
This happens if you remove port 80 as a listening port webcache/em, etc. Oracle claims it needs port 80 for internal communication. For whatever reason the /pls/portal providers are registered in non-SSL. Not sure if Oracle will provide a fix or ?

Error : Portlet could not be contacted ?

Hi ,
Working on Portal 9.0.2.3 , integrated an java application as Portlet to the tab by registering as new portlet provider .
It went on fine till now , recently when i click that particular tab i get this error
ERROR : PORTLET COULD NOT BE CONTACTED .
I tried to refresh the page manualy but still the error exisits.
kindly let me know how to debug this.

Mats,
I found this seems to happen if you are using the fully resolved url to access a page rather than unresolved url.
Unresolved URL:
http://socsbo1.scs.uiuc.edu/pls/portal30/url/page/socsbo_main
Resolved URL:
http://socsbo1.scs.uiuc.edu/servlet/page?_pageid=53&_dad=portal30&_schema=PORTAL30&_mode=3
Why it does this I don't know, but once I made sure the users where using the unresolved URL to access the page the portlet errors went away.
Portal Version: 3.0.7.6.2
Maybe this is happening to you?
