For some reason, I can no longer connect to any NCS Discord voice channels - it just hangs on ICE checking for a few seconds, until briefly saying no route and trying to connect again.
I'm aware that NCS's music bot Red has been playing up recently, but I doubt that it would cause me to fail to connect to any of the voice channels. 


Voice channels in other Discord servers (eg the Android Discord server and The Programmers Hangout) connect fine.


(I am using Spark's DNS servers.)
