[jacobgraf]

I had to rollback to v2.12.3. Hoping this gets patched soon so I can get back onto latest.

[crluehmann]

Just FYI this is a duplicate bug report of many others. v2.12.4 contains some issues.

Rolling back to v2.12.3 seems to be the most straight forward resolution path for now.

Confirm I had to rollback to jc21/nginx-proxy-manager:2.12.3 to fix this issue. Didn't actually prevent my reverse proxy service from working but it wouldn't let me log into the webUI to make changes without a "bad gateway" error

Have you found a solution?

[havedill]

I just force pulled :latest and didn't have this error anymore

[crluehmann]

Yeah, 2.12.5 rolled back the Cloudflare update
