Hello Thwackers,
I spent six hours determining that Microsoft patch KB5010427 was the problem with my SolarWinds installation down issue. About four SW services wouldn't start, so the application was unavailable. The Configuration Wizard failed at about 87% with the message "Could not connect to net tcp//gcgapp02:17777/SolarWinds/InformationService/v3/Orion/certificate." Uninstalling the MS update resolved the issue. FYI... :
Cheers!
