I just moved my Umbraco website to an on-premise server. Now, the site tries to start the upgrade wizard and goes directly to the login, but I’m not able to sign in on the backoffice.
The only thing I see is that the AutorizeUpgrade request is returning a 503 response code. Does any one have any idea about what’s going on here?
