Summary of the issue you are facing:
I updated nextcloud this morning and now a warning came up that wants me to install the notify_push app. So I tried to do this, without luck so far.
I have now read countless other posts but could not find a solution yet. I tried to set it up like mentioned in the documentation, but the reverse proxy does not seem to work.
My setup: Nextcloud is running in an LCX on a Proxmox Host. There it is setup with DDNS and a public IPV6 address whichs works good so far.
Now I tried to install the notify_push app and configure the reverse proxy but it just does not work.

I tried adding the X-Forward-For header with no luck. I also tried changing the Nextcloud URL to localhost. The setup tool always gives me this message:
test output: ✓ redis is configured
🗴 using unencrypted http for push server is strongly discouraged
🗴 push server URL is set to localhost, the push server will not be reachable from other machines
✓ push server is receiving redis messages
✓ push server can load mount info from database
🗴 push server can't connect to the Nextcloud server
See the steps in the README for manual setup instructions: https://github.com/nextcloud/notify_push
The deamon is running but shows no connections to any client.

I cannot just add my server IP to the trusted domains since this IP changes via DDNS, at least that is my understanding of it.
Any help would is highly appreciated since I am out of ideas what I have to change in order to get this to work.
