hello,
i am still getting that error but frankly i have no idea what exactly issue would be? thanks!
There are some warnings regarding your setup.
The reverse proxy header configuration is incorrect, or you are accessing Nextcloud from a trusted proxy. If not, this is a security issue and can allow an attacker to spoof their IP address as visible to the Nextcloud. Further information can be found in the documentation ↗.
Typically that error means exactly what it says. Sadly I don’t have any information to determine which might be the case. You should consider filling out the support post template, and maybe someone who uses nginx will spot the problem.
Can you post your nextcloud config.php here?
What is the local IP of your reverse proxy?
Your …/nextcloud/config/config.php should contain something like this:
e.g. your reverse Proxy is hostet at 192.168.2.100
'trusted_proxies' =>
array (
0 => '192.168.2.100',
),
'overwritehost' => 'your.domain.de',
'overwriteconaddr' => '^192\\.168\\.2\\.100$',
'overwriteprotocol' => 'https',
'forward_for_headers' =>
array (
0 => 'X_FORWARDED_FOR',
1 => 'HTTP_X_FORWARDED_FOR',
),
