Blan screen EAC OWA befor login
I have a problem with EAC and OWA after the last March update. After running these sites from localhost, I have a blank white screen. When I tried to launch it from the Internet, the page was not found. I checked the certificates in IIS management and they are correct - where to look for the reason?

Welcome to Q&A forum!
The first link you provided cannot open normally, could you please check it in your device?
Are there any event ID log when this issue happened?
