Error with mi api configuration

I am raising jitsi with docker on the nated server. But it tells me that the certificates are not valid (for HTTPS_PORT use port 8443 because I have 443 busy) and others, when more than one person wants to enter the link with the call I get this. Does anyone know what the problems are or if they are related?.
Sorry for my English, it’s bad

Try opening the Javascript Console in the browser and check the error there?

They are my logs
