I ran into this as well. Here is a link to an article I wrote detailing the quick fix... (Hosted on Cloudron!) https://i-am-will.com/fix-nextclouds-slow-logon/ Sometimes NextCloud 13 can become inexplicably slow when logging on. One thing that might be happening is you being put on a block list due to entering your password incorrectly. To fix NextCloud's slow logon due to brute force protection, enter this line: ‘auth.bruteforce.protection.enabled’ => 'false', Into this file: /app/data/config/config.php You will need to enter this in the terminal WITHIN the NextCloud app. Go to your CextCloud app and click the terminal button, then click "repair" this will allow you to make changes that stick. Pop in the line above, and finish your repair by clicking "done repair". (Correct me if I'm wrong on any of the details above) Now this will get you working, but itsnt recommended long term. People trying to hack into your NextCloud are stopped by this. Typically this table clears itself every 48 hours or so. Good luck! V/R, Will
