WSUS – Update Services – Error: Connection Error

WSUS

WSUS console kept crashing with the reset console error:

The WSUS administration console was unable to connect to the WSUS Server via the remote API. 

Verify that the Update Services service, IIS and SQL are running on the server. If the problem persists, try restarting IIS, SQL, and the Update Services Service.

So after doing all the normal IIS stuff, got Microsoft involved and here’s what they did to fix it:

  • We checked and ensured that none of the services crashed or stopped after console crashes,
  • We checked and ensured that WSUSPool was also running,
  • We checked and ensured that SQL service was also running on the remote server,
  • We increased the WSUSPool PrivateMemoryLimit to unlimited by setting it to ‘0’ on the IIS console
  • We also increased the Maximum queue length from 1000 to 3000,
  • We stopped WSUSPool and Restarted the IIS service,

We ran below mentioned on SQL to check and find if there are Obsoletes update to clean up but found none

exec spGetObsoleteUpdatesToCleanup

 

  • We found that console was failing to connect with below error as well
  • We removed the WSUS mmc from folder %appdata%\Microsoft\MMC\
  • We tried to connect again to WSUS console but with no avail

 

  • We further investigated and ensured that WSUS s failing to connect with SUSDB as it is timing out
  • We checked and found that SUSDB size was more than 6.5 GB
  • We restarted the SQL Service for instance hosting SUSDB
  • We tried to connect to WSUS console after restarting the service and it connected successfully
  • We see that there were more than 13,000 approved updates on WSUS console
  • This could cause an issue for WSUS to connect as it would take a long time to connect with SUSDB
  • We decided to run PowerShell script to decline superseded updates from WSUS to enhance the performance of WSUS while connecting to SUSDB
  • We ran PowerShell script from below mentioned link to decline superseded updates
