Hello my friend. I am a user on this platform. I do not speak for or behalf of the CubeCoders team.
This is an IP issue, wrong/bad IP. You don’t copy the endpoint from the AMP interface. You have to find your machine’s IP address and forward ports from your router/gateway if needed. Lastly, open ports in your firewall if needed. Although I believe AMP user on Linux does that for you.
You have to make sure you have a public IP as well and that you’re not behind a CGNAT.
Should you need more help regarding the IP forwarding, just reply to me and I’ll be happy to help. <3
