Issue connecting from behind reverse proxy

[issues_fighter]

I have many other threads regarding this but I haven’t found one similar to mine.
I have NC installed in a docker container and I have a nginx reverse proxy that redirect calls to the nextcloud docker container.
I am using everything only from my localnetwork 192.168.1.0/24.
The strange thing is that from my laptop I can access to NC without problems, but from my smartphone I am getting the following error:

We have detected multiple invalid login attempts from your IP. Therefore your next login is throttled up to 30 seconds

the table oc_bruteforce_attempts is empty.
The following is my config.php:

<?php
$CONFIG = array (
  'htaccess.RewriteBase' => '/',

The strange thing is that from my laptop I can access to NC without problems, but from my smartphone I am getting the following error:

Are you using exact same URL to access in both cases? Do you have any errors or warnings under Administration settings->Overview (particularly regarding trusted_proxy, proxies, etc.)?

'overwritecondaddr' => '^172\.22\.0\.8$',

I assume 172.22.0.8 is your reverse proxy? You likely don’t need this conditional.

the table oc_bruteforce_attempts is empty.

This is expected behavior since these days the database backend (slower) is only used for bruteforce tracking if a memcache isn’t configured.

I have been using version 28.0.9 for long time and I have recently upgraded to 29.0.6.1. I am usinging docker-compose.yml in ARM63 architecture.
I have several errors in Administration->Overview :

Sorry my browser default is in italian.
I removed 'overwritecondaddr' => '^172\.22\.0\.8$',
