FW 2.50 GDB connection timeout error

I have attempted this on my main machine running NixOS, as well as a virtual machine running Ubuntu 24.04. For some reason the debugger never connects. It is getting late now, so I can do some more troubleshooting tomorrow.

Looks like you may be using a loader that uses port 9021. These are currently not supported. Use this host instead.

Thank you, that fixed my issue
