Docker with Jitsi

I have installed jitsi stable-6826 (latest) with docker and I am using localhost:8443 to access it. Unfortunately, when I click to join meeting I get reconnection error. Do I have to change anything in my .env file?

# Directory where all configuration will be stored
CONFIG=~/.jitsi-meet-cfg

# Exposed HTTPS port

I’m having the same problem.
