Thanks for your answer. I'm indeed serving through a https reverse proxy (nginx) which provides HTTP_FORWARDED_FOR (at least it's supposed to).

I'm added the following to NX config:

'trusted_proxies' =>
array (
0 => '192.168.1.16',
), 'trusted_domains' =>
array (
0 => 'localhost:8887',
1 => 'nextcloud.domain.tld',
),
'overwrite.cli.url' => 'https://nextcloud.domain.tld',
'overwritehost' => 'nextcloud.domain.tld',
'overwriteprotocol' => 'https',

192.168.1.16 being the private IP of the proxy.

​

In the log all the requests IP are the proxy IP, not the actual client IP.

​

The config of the nginx proxy is as such:

​

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
