This error might come from a mis-configuration on my side, but I searched for hours without any success.
Thanks in advance for those who might spend time helping me on this 🙏

Steps to reproduce

  1. Setup notify_push app and server (docker based)
  2. NGINX configuration done as per the README
  3. self-test is working fine:
> php occ notify_push:self-test
✓ redis is configured
✓ push server is receiving redis messages
✓ push server can load mount info from database
✓ push server can connect to the Nextcloud server
✓ push server is a trusted proxy
✓ push server is running the same version as the app
NGINX configuration (extract) 
#  notify_push is the name of the container in docker
server {
...
    location ^~ /push/ {
        proxy_pass http://notify_push:7867/;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
...
}

Context:

  • full docker setup with Traefik -> NGINX -> Nextcloud (php-fpm)

Expected behaviour

No error found in logs

Actual behaviour

I can see in the log the error Given IP address can’t be parsed
In the example below we can see 1 IPv6 and 1 IPv4 ( 172.18.0.10 being the Traefik IP address)
