Bad gateway?

Hi @i.adzemovic

I have just had a look at this site, I agree that with the nameservers pointing to your host, the site worked OK. Now the nameservers have been changed to Cloudflare, it returns Cloudflare’s 502 Bad Gateway error. I can also confirm that what @sandro said is true, your server does return the 502:

I suspect there is something odd going on that your server returns the 502 when the nameservers point away and that is something you should clarify with them. You should ask why the server is returning a 502. The reason you see the Cloudflare message is because it passes on the 502 from the server.
