Error 522 when Cloudflare is Enable

[demartini]

Hello guys,

First, thank you very much for all this work, I have been following it since the beginning, it saved me a lot of work.

Note: I don't know if my problem is related to this project, but any help is welcome.

I was using version 1 from the beginning and it was working really well. This week, I decided to upgrade to version 2 to take advantage of all the new features and because I needed to do a new installation from the beginning.

I followed all the steps described in the articles:

• Docker Media Server with Traefik 2 Reverse Proxy
• Cloudflare Settings for Traefik Docker: DDNS, CNAMEs, & Tweaks

and I used the files docker-compose-t2.yml, .env.example as a reference.

To be honest, I didn't change anything in the file, just removed what I don't use.

The services I use are:

• traefik
• portainer
• heimdall
• transmission-vpn
• jackett
• radarr
• sonarr
• plexms
• bazarr
• dozzle
• ouroboros
• certdumper
• cf-ddns
• cf-companion

Everything worked as expected.

But when I Enable Cloudflare on Site as described in the article, I can no longer access the services: bazarr.example.com, heimdall.example.com, etc.example.com.

My Cloudflare records:

If I Pause Cloudflare on Site everything works again.

Does anyone have any idea what I did wrong?

Hi @demartini ,

A 522 error happens when a TCP connection to the web server could not be established.
This typically happens when Cloudflare requests to the origin (your webserver) get blocked.
Can you double check that your A record point to you WAN IP Address?

Hello @gzecchi,

Yes, I double check and my A record point to my WAN IP Address. If I pause the Cloudflare service I can access it normally.

But if I enable the Cloudflare I get the 522 error.

I tried everything, but I was not successful. For now I'm using it disabled, which is not very safe.

No activity. Closing this.

Did you ever figure out a solution to the 522 error? I just started to get this error earlier today when everything was working fine yesterday. No clue what changed to cause this error.

What about you @DastardlyDino ? Any solution because I have tried everything I can think of.
