I’ve upgraded a NC instance from 13 to 14 (no errors in the upgrade) and now I can’t login with the web interface, after I introduce the credentials the url is redirected to https://mydomain.com/index.php/login?redirect_url=/index.php/apps/files/ but login screen is reloaded, it’s just a infinite loop.
I’ve compared all the apps in that instance with another that is running fine with v14 and are the same (some people with same problems have solved same issue disabling some app), this instace had spreed installed but it’s disabled, don’t know if that can cause the problem.
I’ve take a look to nextcloud.log, apache logs…but there aren’t errors there, all seems ok.
