Self-hosted server resets the connection immediately on each attempt

Bug Description

I am able to connect between two computers that share the local LAN, but for the normal internet connections I've got cryptic error "Connection Error Reset by the peer".

When I inspect the standard output/error of the hbbs and hbbr, I see no trace of attempted connections. I suspect that there are is some problem with the opened ports.

Or maybe there is some form of connection to either hbbs or hbbr, but it is deemed "too insignificant" for output. Is there any way to increase the verbosity level of messages produced by the hbbr and hbbs?

Is there a way to test the hbbr separately from hbbs? What is the hbbr needed for, anyway? Is there any use case, where I would want it to be run on a separate machine? Afaik, it seems to be used only by the paid version of the program.

How to Reproduce

On headless Ubuntu 22.04 I've created an LXD container with Ubuntu 22.04, I've installed there these two packages to have private Rustdesk server instance:

rustdesk-server-hbbr_1.1.10-3_amd64.deb rustdesk-server-hbbs_1.1.10-3_amd64.deb

I've made sure the relevant services are up and running. In particular, the programs are run with the following command line arguments:

hbbs -r 139.162.226.242 -k _
hbbr -k _

There is a valid id_ed25519.pub in the working directory of both programs.

I've also made sure the following ports are forwarded to host:

tcp:21115
tcp:21116
tcp:21117
tcp:21118
tcp:21119
udp:21116

In the client's settings, I filled in the server's IP for the "ID server" and "Relay server" fields, as well as the Key.

Expected Behavior

Client connected to another's client remote desktop.
