Bind to other address than 0.0.0.0 fails, if defined in config file

[cRoCx]

The config file doesn't seem to accept addresses other than 0.0.0.0. Tried it with localhost, 192.168.0.0, 192.168.0.100 (own ip address), ::1 and localhost,192.168.0.100,2466:44:2234::100.

• Version:
  wayvnc: 0.7.2
  neatvnc: 0.7.1
  aml: 0.3.0

• Try to reproduce while capturing a trace log:

  • wayvnc -Ltrace | tee wayvnc-crash.log
  • Output:

error: XDG_RUNTIME_DIR is invalid or not set in the environment.
ERROR: ../src/main.c: 402: WAYLAND_DISPLAY is not set in the environment
ERROR: ../src/main.c: 1495: Failed to initialise wayland

• Describe how to reproduce the problem
  Fresh install of Raspberry Pi OS Bookworm on Raspberry Pi 5. Enabled VNC via raspi-config (enables wayvnc). In /home/username/.config/wayvnc/config changed address=0.0.0.0 to address=192.168.0.0 or anything else. Restart (sudo reboot).

My goal was actually to try binding to localhost, a custom IPv4 VPN address and another custom IPv6 VPN address (address=localhost,192.168.0.100,2466:44:2234::100) and then disable the authentication. I wanted to test this, since address=0.0.0.0 and adding user=test and pw=test also doesn't work. The latter is another problem I might report later in a seperate issue.

The only combination that works is address=0.0.0.0 and having enable_auth= either true with default certificates and default user auth (no seperate credentials in config file) or false.
