Also having the exact same issue since about 3 weeks. We have an enterprise self hosted workspace (150 users). Tried everything, even redeploying completely from scratch but the issue persists. We tried version 7.13 and also 8.4.1. Does not matter In the app randomly some audio files are not playing, but never the same ones. Its mostly random. When switching between chats everytime different files will not work. Also in the app all audios display as 0 seconds.
This I can be fixed by converting them from aac to mp3 like I posted in the thread back in 2021 when I had the same problem:
Audio Recordings do not load (randomly) - Community Support - Rocket.Chat
We use nginx as a proxy but also tried traefik.
In the browser everything works perfectly.
When opening a chat in the app I can see in the nginx logs that all the files get served corretly and returned with status 200:

Can someone please look into it. The users are using audio messages extensively and this Bug(?) drives them crazy
