NCP: reverse proxy configuration leads to too many redirects error

Simon2018 · July 10, 2022, 7:51am

I setup the following docker container:

nextcloud
nextcloudpi
reverse-proxy
sharelatex (not important, just for testing)

I configured the reverse-proxy so that is redirects subdomains of my main domain to the other docker container. Its working well for nextcloud and sharelatex, but not for nextcloudpi. How do I configure it correctly?

nextcloudpi logs:

$ sudo docker logs nextcloudpi

any hints here or suggestions to improve my question?

Especially the config.php is interesting to me. I link to posts which did not help:
phip1611 => many errors from the begining. Got it running after some time, but also had the “too many redirects” error.
This forum => no config.php. Not enough info for me to configure.

REAPERSbattlecry · July 13, 2022, 2:19pm

Not sure if I can help you. I use the ngnix reverse proy manager and it runs like a charm.
Have you added the lokal IP to the trusted proxies in the ncp panel?
Do you use any apps which are little bit complicated with proxies (talk, office)?

Simon2018 · July 13, 2022, 4:07pm

When I set the trusted proxies, it added this part to the config.php, but I still have the same error:

'trusted_proxies' =>
  array (
    0 => '192.168.103.34',
    2 => '127.0.0.1',
    1 => 'localhost',
  ),

I also tried the IP of the reverse proxy docker container (172.21.0.7) as trusted proxy, but it leads to the same error.
192.168.103.34 is the ip of the server where the docker container are running on.

Simon2018 · July 13, 2022, 6:38pm

ok I solved it the following way:

Renamed config.php to config.php.backup
go to the nextcloud dashboard (e.g. http://192.168.189.23 in your browser). Enter the passwords and database data from config.php.backup. Set new admin password.
add the ip of the docker container host (so basically the ip of your server) to the trusted domains.

Here is my new autogenerated config.php:


<?php
$CONFIG = array (
  'instanceid' => 'asdh5345ju',
  'passwordsalt' => 'eregrgre43543hthr45uu4h',
  'secret' => 'KQJdasfasdfadsgrhreht',
  'trusted_domains' => 
  array (
    0 => '192.168.103.34:82',
    20 => 'kaese.eu',
    21 => 'kaese.spdns.eu',
    22 => 'cloud.kaese.eu',
  ),
  'datadirectory' => '/data/nextcloud/data',
  'dbtype' => 'mysql',
  'version' => '23.0.2.1',
  'overwrite.cli.url' => 'http://192.168.103.34:82',
  'dbname' => 'nextcloud',
  'dbhost' => 'localhost',
  'dbport' => '',
  'dbtableprefix' => 'oc_',
  'mysql.utf8mb4' => true,
  'dbuser' => 'ncadmin',
  'dbpassword' => 'agrrgreggregre',
  'installed' => true,
);

Its just quite unfortunate that all my files and addons are then gone. So I will have to backup them and reinstall them when I try it on my productive system.
