SharePoint 2016 : Resolve UPA Endpoint Issue

  • Article

SharePoint 2016 UPA endpoint issue occurs because of the changing of the service instance to a different server. Today, SharePoint gave us a little tough time again. Aahh! It is normal if you are a SharePoint Admin.

Problem

Due to some capacity issue, we decided to add more servers into the farm. After successfully adding the servers into the farm, we shuffled the services from existing servers to the newly added servers (as per our plan). We successfully moved the Distributed Cache Services, App Management Service, Managed MetaData Service, and Central Admin except for the User Profile Service application. When starting the User Profile Service instance on the new Server and stopped it from the existing one, SharePoint threw an error, i.e. News feed not working, and Site content page displayed the following error.

"We're having trouble loading some parts of this page, but your documents aren't affected. While we work on fixing it, you can continue using your documents like you normally would."

If we try to use UserProfile asmx from InfoPath farm, we get the following error.

“The SOAP response indicates that an error occurred on the server,

Server was unable to process request. ---> UserProfileDBCache_WCFLogging :: ProfileDBCacheServiceClient.GetUserData threw exception: The HTTP service located at http://kf-sp1:32843/3da75a6367304a72a5e80573218d2313/ProfileDBCacheService.svc is unavailable. This could be because the service is too busy or because no endpoint was found listening at the specified address. Please ensure that the address is correct and try accessing the service again later. ---> The remote server returned an error: (503) Server Unavailable. “

Troubleshooting

We checked the ULS logs and found this entry which clearly showed that the SharePoint (for some reason) was still looking for the old Server for UPA Service Instance.

We tried the following things to resolve the issue.

  • Run IIS reset on the Server where we stop the UPA instance and other Apps & DC servers but not on WFE.
  • Clear the config cache on all servers in the farm. We even saw the XML file in the config cache folders contain the correct endpoint for UPA.
  • Restart the timer services on the servers.
  • Make sure topology service is working on all servers.
  • Run the “Application Addresses Refresh Job” timer job (which run every 15 minutes). This job is responsible to update the connection address in config.
  • Removed that server from the farm (yes, you read correctly, we removed the server from farm) but still no luck.

Resolution

Finally, we cracked it. Seems like the endpoint was cached on the Web Front-end Servers. As soon as we reset the IIS on all Web front-ends, SharePoint started working as expected and picked the endpoint from the new Servers.

In the future, if you see that SharePoint is not picking the new endpoint, please do the IIS reset on the web front.
