Cloudflare with Nginx Proxy Manager Issues (alien.top)
submitted 10 months ago by [email protected] to c/[email protected]

I’m trying to setup a Cloudflare tunnel to Nginx proxy manager to access all my self hosted services externally.

If I have my tunnel forward to http://nginx:80 and have force TLS turned off in Nginx proxy host everything works fine.

If I turn on force TLS I get a too many redirects error. I did some googling and found that you need to turn on full encryption rather than flexible in Cloudflare to fix this and I tried that and I still get the same issue.

If I change the tunnel to forward to https://nginx:443 I get a 502 bad gateway error, even if I turn off TLS verify.

Can anyone please help me fix these issues?

Why not just use the Cloudflare tunnel to connect directly to the services in question, rather than tunnel > npm > service, out of curiosity?

I’ve got a bunch of my services behind my tunnel, be it http or tcp services, and just point the tunnel to those services directly. Services I don’t want publicly accessible I put behind Cloudflare access which goes to my Keycloak instance for auth and then to the service if successful. Ended up getting rid of traefik as a reverse proxy entirely when I swapped to using Cloudflare tunnels.
