for some reason {ip} shows 0.0.0.0 but {port} shows correct.
this is on one server where it shows wrong ip, other server shows correct IP.
incorrect server runs on linux, correct one runs on windows, if that makes a difference.

Noticed these errors when reloading

(09:44:44) | [Discord Ext] Discord connection closed uncleanly: code 1006, Reason: An exception has occurred while receiving.
(09:44:44) | [Discord Ext] Attempting to reconnect to Discord...
(09:44:44) | [Oxide.Ext.Discord] Error: tried to create a heartbeat when one is already registered​

i suspect the oxide.discord.dll file needs to be updated.

Updated the oxide.ext.discord.dll, rebooted server.
deleted config, unloaded plugin, reloaded, reconfigured config
Bot still giving ip as 0.0.0.0:portnumber

You can write the IP Manually perhaps? 124:12blabla:{server.port}

Perfect, thanks!
Not really the ideal solution, but a solution none-the-less :)
