Unable to get voice or video from some other people randomly

Hi,
I have few problems with my setup,
Some people are unable to get voice or video from some other people randomly.

on the client side using chrome or firefox doesn’t change anything and leave and join can solve the issue (or it can make things worse), I didn’t get the problem myself and it’s like I speak an alien language when I ask to open the devtools with CTRL + SHIFT + I …
I don’t even know if it’s a problem with my clients’ bandwidth … or maybe our bandwidth

Do you have any idea about my problem ?

If audio is not heard from part of the people, but not all, we call this audio island.
We had found potential issue for this and it will got with the update we are preparing this week.

thanks,

I just updated by a classic apt update + apt upgrade + resolve config and I have few problems with prosody modules:

The share folder does not exist anymore

visio.example.net.cfg.lua

plugin_paths = {"/usr/share/jitsi-meet/prosody-plugins/", "/usr/local/lib/prosody/modules"}

prosody.cfg.lua

plugin_paths = {"/usr/share/jitsi-meet/prosody-plugins/"}

In the past I solved an jitsi-meet-tokens installation issue with

$ apt install luarocks
$ apt install cmake git lua5.1-dev
$ git clone https://github.com/evanlabs/luacrypto
$ cd luacrypto
$ luarocks make
$ cd ..
$ luarocks install luajwtjitsi
$ apt install jitsi-meet-tokens

do you think there is a link ?

I’ll restore my snapshot to try the procedure again
