last day all things is working fine, i had setup nginx proxy for node application https://ccscheck.com/
but today my app not working geeting error msg 502 Bad Gateway
openssl s_client -connect ccscheck.com:443 -servername ccscheck.com
connects just fine.
https://ccscheck.com/ takes a very long time then returns:
504 Gateway Time-out
I suspect there is some user agent check that is redirecting to a non-existing backend system/port.
I would review the last changes and confirm all backend systems are reachable.
Or maybe a reboot can get things going again…
SSLLabs can also connect and returns "A"
But also shows:
https://ccscheck.com/ (Request failed)
Test duration 139.88 seconds
HTTP status code Request failed
HTTP server signature Unknown
This usually means the node.js backend has failed for some reason. Try restarting it.
If that doesn't work there there should be a message in /var/log/nginx/error.log
indicating what the problem is.
