Hi,
Can someone point me to some troublshooting guide of Bad Gateway issue? I had a seafile server docker running smoothly in Proxmox for months. Two days ago my SSD failed, so I put the new one in and restored a snapshot from previous night. All VMS restored just fine, but Seafile is throwing nginx error “Bad gateway”. I’ve looked in the nginx log, but it only states “Connection refused while connecting to upstream client”. I could not find anything in other logs. There were no changes made prior the disk failure and everything was running smoothly. I’ve tried restoring earlier snapshots but same issue.
Any hints will be apreciated.
Thanks
Edit: so I’ve managed to narrow the problem to Letsencrypt. It appears above issue happens when it is enabled. When I disable it, but keep the force https enabled then https is working fine. What’s interesting, the letsencrypt.log is not updating since the day my ssd failed.
