The route checker is not working. I get a message that says "502 bad gateway." This has been going on all day. Any solution?

Just renewed my route and now it's not working. Was working fine earlier. Using Stalker Client on Kodi 16 and it says "Stalker Client Authentication Failed." I did an IPTV reset and still nothing. Help.

I just made a donation and I'm trying to get this to work, with no luck. I'm using Kodi with Raspberry Pi and the MAC address for my Pi begins with 78:da:38. When I try to add my MAC address in my donation check, it says the address is invalid. What's the fix?
