All,
In last 2 to 3 instances during Windows or ESRI chrome patch installation - I could see Portal SSL certificates are corrupted and because of that Portal application is unavailable and throwing the message "Portal could not access any of portal machines. Please contact system administrator".
Does any one experienced these kind of issues / or they known technical issue with Portal during patching event.
One important thing is - when Windows patching is abandoned in middle or something happens during patching, portal SSL certificates are corrupted and lost.
Env: Windows 2012. Portal 10.4.1 federated with ArcGIS Server.
