Hey, I've recently upgraded one of our clients sites from umbraco 8.13.1 all the way to 13.0.1 - after some struggling I've managed to sort it out. BUT I've recently discovered that when I log into the backoffice I keep getting "Session timed out." not even 60 seconds after I've logged in. I've tried setting up the TimeOut value in appsettings.json to a multiple different values without any success. I've scoured the internet and I cannot find anything that seems to resolve this issue for me. Is there anyone who've encountered this problem and if so how did you resolve it?

Do you have multiple client projects running at once/quick succession? I notice this sometimes gets a bit weird when I login to one client site and then another

Negative - but I seem to have solved the issue by creating a new user with the default admin account

Glad you solved this Sam. I wonder if this is related to 'Concurrent Logins' which are now disallowed by default in v13. Maybe try to set 'AllowConcurrentLogins' to 'false' to see if it solves the original problem. But going forward best to avoid using a shared login. See the Unboxing video on YouTube for more info: Not entirely sure it is that, but might help anyway 🙂
