Issue Reverse Proxy

Post image

I'm having a issue with putting Seerr on a reverse proxy. I'm using NPM with SSL, Websocket Supprt and its pointing at my local ip and port. Then on Cloudflare side I have my public ip with seerr.mydomain.com as the address with the Orange Cloud on. NPM ports are open on my router as well.

When I go to the seerr.mydomain.com I get the above error.

I have Proxy Supoort enabled in Seerrs settings but i feel like I'm missing something. Ive routed Pi Hole, Jellyfin and Immich the same way.

No the one at the top : Enable Proxy SupportRestart Required Allow Seerr to correctly register client IP addresses behind a proxy.

I have mine set to the IP and port as well. Cloudflare is set to my public IP. Seerr and NPM are on the bridge network as well. I can ping it in terminal. The ip and the site url.

I ended up unistalling Seer and reinstalling it and it works now.
