Forum Forum Error 502 Bad Gateway

[Energeez]

I cannot read forums on the computer anymore :
As soon as i click on a topic title this happens.



I want to figure where this problem comes from and how I can fix it.

I can access the forums boards (categories) and post a new topic, the 502 error only occurs when trying to read a topic (any topic, anywhere on forum).
Problem seems to disappear when I restart computer (or browser ? haven't tested extensively) but it will happen again before an hour. Once 502 errors are happening there is no coming back, it stays like that until I reboot something (browser, or computer, I could try if someone needs to know).

I tried from the phone and it works just fine, so I'm quite sure it's a problem on my side and not Warmane's ?

Any help is welcome & appreciated.
