Tile view not working & video freezes on fresh install

Hey there,

I did a fresh install yesterday to give jitsi a try. I hosted a conference with three people.
Only I was able to switch to tile view. Also, the video of the other participants froze randomly.
My setup: Cloud Server with 1 vCore and 4GB of RAM.
Is there any possibility for me to investigate, what’s wrong here?

Cheers,
Alex
