Error Message

My website https://uddipan.wuaze.com/ (IP: 185.27.134.201, Server: vol14_1) is showing
intermittent 502 Bad Gateway (openresty) errors throughout the day.

Resource usage from VistaPanel:

  • Daily Hits: 280 / 50,000 (0.56%)
  • Daily CPU: Near zero
  • Entry Process Failures: 2 / 200 (1%)
  • Disk: 27 MB / 5,000 MB
  • Bandwidth: 203 MB / Unlimited
  • Inodes: 128 / 80,000

Everything is extremely under limits. The 502 happens randomly on
both index.php and address.php. Simple test.php also returns 502
sometimes. This looks like a server-side issue on vol14_1.

Can someone check if vol14_1 is stable? Multiple users on this
volume may be experiencing the same issue.

Thanks.

Welcome to the forum. Please don’t make multiple posts about the same issue, it won’t help get a faster reply.

to summareise:
A 502 Bad Gateway error is an HTTP status code indicating that a server acting as a gateway or proxy received an invalid response

This can be long running or intermittent problems caused by many things including:

  • the server getting overloaded (too many request)
  • incorrect server config. Unlikely in this case, as that tends not to be intermittent, that would error every time.

So if it’s intermittent, it’s likely that there isn’t a specific issue causing it.

I mostly agree with what @dan3008 said. A few other reasons that come to mind:

  • PHP scripts reaching the 60 second execution time limit may also trigger a 502 error.
  • In some particular cases, crashing or incorrectly responding PHP code may also trigger this error code.

When you do get these 502 errors, can you check how long it takes for that error to arrive? If it takes 60 seconds for that error to appear, it’s definitely the PHP time limit.
