I can't open microphone, camera and others can join the meeting, how do i fix it?

Maybe share your jicofo and prosody config. Something is wrong with the configuration.
How did you install?

Is jitsi.example.com your actual domain? If so, try restarting prosody to see if that helps. Be sure to share your configs as requested.

I installed jitsi-meet according to Self-Hosting Guide - Manual installation, I’m not sure if all the libraries are installed or not.

config /etc/prosody/prosody.cfg.lua

That is your problem, check the warning on the top.

I don’t understand, what should I do???

Use the quick install guide and first remove the manual configs.

If I want to edit code jitsi meet, what do I have to do when it’s not manual installation?

Read the forum :slight_smile: [How to] How to build Jitsi Meet from source: A developer's guide

I’ve tried doing this but it still has the same problem.

what should i do

Follow the quick install guide, the uninstall part.

Purge also prosody if you are not using it for anything else.

And delete /etc/jitsi and /etc/prosody folders, and try again.

If then you still have problems, upload the js console log here.

Thank you very much. I will try and tell you the result.

After trying your advice. it is available Thanks for the good advice.
