Lot of 502 Bad Gateway nginx errors every day

Many times the server is waiting/trying to load during half minute until I get a 502 Bad Gateway error. Then I have to refresh the page and the problem is gone.
What is happening to the server? how to solve this issue?

On which website do you experience the issue? All sites seem to be working fine from here.

Yeah! I experienced that last night at 12:00 am to 1:00 am my site was social-build.rf.gd
Right now its working fine.

Yes, this host service is very unstable

I’m monitoring various websites and IP addresses myself and I have not been able to recover any errors myself. You’re not the only one reporting this issue, but so far I have not seen it myself.

Error right now… loading… waiting… error 502… refresh and fixed.

I can set up monitoring for you to see if I can catch the error while it’s in progress. But you still haven’t told which website you’re actually referring to.
