Please help,the page is black and there is no record button!

Are there errors in the js console?

yes,this is jvb.log and jocofo.log.

When I did not configure jibri, two people would go wrong when entering the room. When I configured jibri, it was the situation I just said!

Leave jibri for now, first you need to make sure opening 3 tabs works on the deployment.
jvb and jicofo cannot connect to your prosody, try fixing that.

Thanks!You mean that two people can talk normally before deploying jibri.

I mean 3 people can talk.

Can jibri only record scenes with more than 3 people?

I should turn off jibri now, so that 3 people can be online at the same time by adjusting jitst, and then configure jibri recording after success.
