App Url is somehow not working

[benni347]

I am getting this error when trying to access a service behind tinyauth. From the attached trace log we can see AppURL = https://auth.foobar.vip so I don't understand why I am facing this problem that the url is wrong. Also my redirect URI to zitadel is also somehow auth.at.foobar.vip

Somehow had an orphaned container, which had the same dns name.
