Jitsi meet does not display the interface in the browser

jitsi meet on remote server does not show interface. install it on a server with LXC container. it is supposed to be published to be accessed remotely with a domain. However, when placing the domain address in the browser to enter, it seems that it would work and show me the jitse meet interface, but it comes out black, that is, it does not show the jitsi presentation screen to create a conference room. Please someone help me indicating that it could be that problem to solve it.

Check your browser console for errors (Shift+Ctrl+I or F12)
It could be something small like a syntax error in config.js (missing comma at the end of line) or something more complex. A black (grey) screen could mean that it’s partially loaded, most of the time this is due to a syntax error on config.js.
