Steps to reproduce

  1. podman run -d --rm --name nextcloud --network nginx-network nextcloud
  2. config.php
<?php
$CONFIG = array (
  'htaccess.RewriteBase' => '/',
  'memcache.local' => '\\OC\\Memcache\\APCu',
  'apps_paths' =>
  array (
    0 =>
    array (
      'path' => '/var/www/html/apps',
      'url' => '/apps',
      'writable' => false,
    ),
    1 =>
    array (
      'path' => '/var/www/html/custom_apps',
      'url' => '/custom_apps',
      'writable' => true,
    ),
  ),
  'instanceid' => 'oc8q4k57uxw8',
  'passwordsalt' => 'yx1I5LCWvw+MZK2HtpEeA2XF0pgubt',
  'secret' => 'SQmZu2GRO5EQBOn3arKBT3vuND/XoW4mhN2Dtzd+2kwLkVGl',
  'trusted_domains' =>
  array (
    0 => '192.168.2.81',
  ),
  'datadirectory' => '/var/www/html/data',
  'dbtype' => 'sqlite3',
  'version' => '18.0.3.0',
  'overwrite.cli.url' => 'http://192.168.2.81:8080',
  'installed' => true,
  'trusted_proxies' =>
  array (
    0 => '10.0.0.0/8',
    1 => '172.16.0.0/12',
    2 => '192.168.0.0/16',
  ),
  'overwritewebroot' => '/nextcloud',
);
  1. podman run -d --name nginx -v nginx-conf.d:/etc/nginx/conf.d/ -v nginx-certs:/etc/nginx/certs/ --network nginx-network -p 80:80 -p 443:443 nginx
  2. default.conf
server {
    listen 80 default_server;

    server_name _;
    return 301 https://$host$request_uri;
}

server {
    listen       443 ssl;
    server_name  192.168.2.81;

    ssl_certificate     certs/192.168.2.81.crt;
    ssl_certificate_key certs/192.168.2.81.key;

    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

    location /nextcloud {
        proxy_set_header X-Forwarded-For   $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-Host  $host:$server_port;
        proxy_set_header X-Real-IP         $remote_addr;
        proxy_pass                         http://nextcloud:80;
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}

Expected behaviour

Redirect to nextcloud login under https://192.168.2.81/nextcloud/login

Actual behaviour

Infinite HTTP 302 Found loop with Location https://192.168.2.81/nextcloud/login`

Changing location /nextcloud { to location / { in default.conf and removing overwritewebroot in config.php results in a working nextcloud instance under https://192.168.2.81.

I played around with htaccess.RewriteBase, overwritehost, overwrite.cli.url, ...

No success.

Just install nextcloud vanilla plugin from freenas. Nextcloud can be accessed by IP or server name (nc2) and is working as design.

Adding the 'overwritewebroot' => '/nextcloud' in the config.php, and got the too many redirects.

Here are the outputs of curl -sILk nc2/nextcloud | egrep 'HTTP|Loc' | sed 's/Loc/ -> Loc/g' for both without and with the overwritewebroot

Without the overwritewebroot :
[user@anotherserver]$ curl -sILk nc2 | egrep 'HTTP|Loc' | sed 's/Loc/ -> Loc/g'
HTTP/1.1 302 Found
-> Location: http://nc2/login
HTTP/1.1 200 OK
[user@anotherserver]$

Without the overwritewebroot :

Changing location /nextcloud { to location / { in default.conf and removing overwritewebroot in config.php results in a working nextcloud instance under https://192.168.2.81.

thanks , in my case adding the "location /nextcloud" instead of "location /" in 443 section of proxy config solved the issue

Hello. Do you mind sharing which line in which proxy config file you edited?

I had this exact issue and have it fixed. In my opinion this proves it is not an issue/bug with nextcloud but faulty config in the reverse proxy (although I found it hard to find proper documentation for this).
See here nextcloud/docker#401 (comment)
