Problem Description

Issue

I’m running into an issue where I cannot connect to the AMP web server through my external IP. I have checked everything to make sure that my ports are forwarded correctly and that my machine isn’t blocking the request.

I can connect to the web server through a internal ip, but when I try to connect to it through my external IP, it doesn’t load. However, the minecraft server that I’m running can be connected to through the external IP so I know my ISP port forwards are working. I also checked the canyouseeme.org results to ensure the default web server port of 8080 is forwarded as well. I also checked all of my firewall rules and my configs for AMP that I configured through the internal ip access.

Reproduction Steps

  • Start AMP and connect to it through internal IP address at port 8080. This works fine.
  • Try to connect to external ip at port 8080. This does not work.
  • Checked port forwards to ensure it is set up properly. This is complete and I have checked multiple times through different means.

What’s the output of ampinstmgr status?

Odd. Could be your ISP blocks 8080 given it is a common port 80 alternative, and some ISPs block web hosting

Or it could be a NAT hairpin issue. Have you tried connecting on your public IP while outside your network (like on your phone)?

This worked, but if you could, view the discord thread here please, I will be more responsive as my notifications aren’t going through here.
