Upgrade to 2020.2.5 failed with Container storage is not initialized on Additonal Web Server.
I went from 2020.2.4 to 2020.2.5, everything else worked, just the Additonal Web Server failed.
Re-ran it a couple of times, with a reboot before the last attempt, it fails with the message;
Services configuration failed:
• Connection to SolarWinds® Information Service did not succeed.
Last error: RunQuery failed, check fault information.
Container storage is not initialized. Reason: InvalidOperationException:Not yet initialized
