Thank you for your help. I can't connect to "he.relayable.org", actually I can't open it via browser too. I tried "ca.relayable.org" and it worked. I checked if "he.relayable.org" is blocked in Turkey but it isn't. Maybe server company doesnt't allow specific IPs of my ISP, I don't know. How can I see all specific geo relays to find closer location than Canada except Helsinki as a workaround?
