Bug description

Full server log: https://gist.github.com/Cragsand/a5f838d2fe3738312d54d5a9cfaf9f8d Full client log: https://gist.github.com/Cragsand/577454591653bb0550cf9e5cb9d3391b Version: voicechat-forge-1.20.1-2.5.15.jar

Logs show that authentication is successful, ports are open and forwarded but still unable to connect and use it ingame. Opening to LAN and running a client on the same computer works but not when hosted as a server.

Using the ping tool from a windows PC returns "timed out after 10 attempts"

There are quite a lot of these entries in the logs but no error is shown. [VoiceChatAuthenticationThread/INFO] [voicechat/]: [voicechat] Trying to authenticate voice chat connection

Looking at a snippet from the server log it seems authentication works correctly:

Config voicechat-server.properties:

# Setting this to "-1" sets the port to the Minecraft servers port (Not recommended)
port=24454

# To bind to the wildcard address, use '*'
bind_address=

Port 24454 udp is opened in the server firewall and forwarded. Server is hosted on a Kubuntu linux PC using pufferpanel and modded server works fine otherwise except voice chat. I also tried changing to different ports, 40001, 54237 etc and configured port forwarding accordingly since that seemed to be general advice offered elsewhere although I don't know why that would make much difference.
