Discord voice isnt working

i have my openwrt setup pretty default except SQM QoS but i have that disabled right now due to this issue im having. when i try and join a voice channel on discord i get "RTC Connecting.... No Route" and it just repeats. i can ping discord.gg and get a response and cloudflare isnt blocking my ip and my ISP isnt blocking discord or cloudflare in any way. it was working fine before i switched to this router that has openwrt on it

I think it is rather unlikely for OpenWrt to be the root cause of this problem - have you engaged with discord support (if any) to debug the issue?

Is this from within your browser, using discord via its website, or via the dedicated app? It might be worth trying to switch from one to the other and see if you can reproduce the issue.
