Other service on another port on Jitsi Meet Server not work

Jistsi is different in docker and jitsi-keykcloak is in docker on the same host. jitsi-keykcloak runs on port 3000. When accessing http://jitsi-meet.host:3000 , an ERR_SSL_PROTOCOL_ERROR error occurs. Even if not http://IP_JITSI_MEET-HOST:3000, then the request passes. How to configure http://jitsi-meet.host:3000 to work?

You should probably ask the jitsi-keycloak developers.
