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!

Drop the table correct the issue also.

The nginx reverse proxy in front of the app is already setting that header https://git.cloudron.io/cloudron/box/blob/master/setup/start/nginx/appconfig.ejs#L104

Not sure if apache needs some further configs for this as well? The local apache config of the app is at https://git.cloudron.io/cloudron/nextcloud-app/blob/master/apache/nextcloud.conf

That's how I understand the documentation here : https://httpd.apache.org/docs/current/en/mod/mod_remoteip.html#remoteipheader

Nginx forward the the header to apache/NextCloud, but apache/NextCloud don't read it as "the real IP"

Not sure if apache needs some further configs for this as well? The local apache config of the app is at https://git.cloudron.io/cloudron/nextcloud-app/blob/master/apache/nextcloud.conf

The anti-ddos embeded in NextCloud probably blacklist my reverse-proxy IP ;
Also, Where is the apache configuration? In order to avoid this, we need to add "remoteIPHeader X-Forwarded-For" in the apache vhost for NextCloud in order to detect the real IP add.
