Hi there,
i’m new to Cloudflare i this 520 Error message makes me crazy. A few days ago i had 16 of 20 of my Services configured WITH Cloudflare Proxy. I like the way that Cloudflare handles my SSL Certificate, so i would love to use this feature. The 4 other Services had 520 HTTP Error issues so i decided to publish them without Cloudflare proxy (DNS only) and do letsencrypt. So far so good.
A few days ago, i needed to migrate the most of my services to another Proxmox Server. I changed the Nginx Proxy Manager to adress the new virtual machines and those services are up and running without issues. Only Cloudflares gives me an 520 error. When i deactivate Cloudflare Proxy and do DNS only, the services work fine.
I could handle ignore this issue, let Cloudflare proxy deactivated and use letsencrypt certificates. But i would really love to use Cloudflare as Service here. I already cleaned browser cache and Cloudflare cache. Waited a few days. Switched to developer mode. I dont know WHERE the issue is. Services are up and running, reachable from the network and do not respond with an HTTP Error Code.
There a no log entries in the nginx log.
Maybe someone can help and has experiance with that?
The Services that dont work anymore:
- Bitwarden
- 4 own developed Rest API
- Heimdall Dashboard
- Funkwhale
- Paperless-ng
- MailMonk
- Mailcow Mailserver (Only the Web UI)
- Nextcloud
- 2 Static Webpages (gohugo websites)
Thanks.
Best Regards
Marco
