TSD Proxy V2 and Nextcloud

[janreinhardt]

Please I need some help with TSD Proxy and my Nextcloud container. I have googled and read a lot of stuff already, still its not working.
This is the situation:
TSD Proxy V2 docker container
Nextcloud: latest docker container
Both are in the same docker network, running on a Raspberry Pi 5 (machine name ’raspi5’ )

Nextcloud docker run:

docker run -d --name nextcloud --restart unless-stopped \
(…)
-p 8010:80 \
-p 8443:443 \
-l tsdproxy.enable="true" \
-l tsdproxy.port.1="443/https:80/http" \
(…)
nextcloud:latest

TSD Proxy tsdproxy.yaml :

lists:
    nextcloud:
        filename: /config/nextcloud.yaml
        defaultProxyProvider: default
        defaultProxyAccessLog: false

nextcloud.yaml :

nextcloud:
  ports:
    443/https:
      targets:
        - http://raspi5:8010/

This setup is working, but Nextcloud does give me this security warning = some stuff I want to use (for example OIDC login) is not working since Nextcloud is not in „real“ https-Mode.

How do I address the nextcloud container on port 443? I have tried lots of port variations, but I cant get things to work :-(
What settings in TSD Proxy does it take (what container label, what settings in the *.yaml files) ?

Thank you for your help!!

solved it myself!
that red error sign is now gone.
Both the TSD Proxy and the Nextcloud container are running in the same docker network, but its IPV4 IPAM Subnet was not added to the Nextcloud config.php correctly because I was changing around docker networks earlier.
Edited

'trusted_proxies' => 
  array (
    0 => '172.19.0.0/16',
  ),

and everything is fine now.
