Bad gateway Error code 502

[wktan96]

Hi all,

My Nextcloud is suddenly showing a 502 gateway error. I'm using Cloudflare Tunnel as my reverse proxy. I tried resetting the instance based on the guide and restore my backup, but the gateway error persists. I have confirmed that the configuration in Cloudflare Tunnel has no issue because it works on a newly created instance. I reset and installed the new instance with the same domain name and compose file without restoring my backup, so my backup somehow has a misconfiguration somewhere, but I'm not sure how to check further.

Appreciate if anyone can help me with this issue.

*Disabling my ufw firewall and adding APACHE_IP_BINDING: 127.0.0.1 in the compose file below (It was working fine previosuly without setting APACHE_IP_BINDING) doesn't help
*I launched my compose file below (nextcloud-aio-mastercontainer) via Portainer CE 2.33.7 LTS
