Pinhole/Adguard cause cloudflare error 522 when enabled

[dlawrence]

I hope someone can help me.

 

My setup includes pihole, nginx proxy manager, and my various tools (nextcloud, sonarr, radarr, organizer etc) and I use cloudflare. I also recently moved to a .ovh domain name.

 

I've been using my setup for years, however after upgrading to 6.12.4 when I try to connect to my various applications via domain name I get a cloudflare error 522. I have tried removing the proxy/ changing the security on cloudflare with no joy. I finally found if I disable pihole it works fine. I tried deleting pihole and reinstalling it thinking the problem was a rouge setting that I couldn't find. That didn't work. So I tried an alternative Adguard and was also getting the 522 error when it was enabled.

 

I have searched google and various forums with no success.

 

I'm at a loss and don't know what to try next any suggestions would be welcome. YouTube videos etc helped me to get my setup to were it was, so I'm a novice with regards terminal etc so please be gentle 🙂

 

Thanks
