502 error only from certain countries


Hi Guys,

I got a complaint from one of our clients, that their site seems to be inaccessable from some european countries and when i checked (tried to get to the website over a VPN from Sweden) i indeed got a 502 error thrown back.
The error page suggests, that there is some issue with the host server, but i already checked and the IP doesn’t even reach the server, but seems to get blocked before already.
Can someone tell me what the issue is here?

The site is https://e3zine.com and the Ray ID was:
Ray ID: 390387b7ef3e0c2f



Are you getting the plain page with the nginx error or the Cloudflare branded version? You can find some useful tips here:


Hi Ryan,
I see the branded version and i have already read through these tipps. The problem is, i contancted our server host and they tried to go to the website over a proxy from sweden and the server didn’t even get the request from the ip. So it must be blocked somewhere before the host server.
Any thoughts or ideas?
Regards Max

Since it sounds like you have already whitelisted Cloudflare IPs at your origin, the next step would be to submit a ticket to support, login to Cloudflare and then contact Cloudflare Support
