I also encountered this issue. After deploying directly with Docker Compose, I found that the requested address did not include the port. I understand that it should only work with a domain name. Is there a way to support IP + port?"
some config：
chatapp:
image: ghcr.io/muke1908/chat-e2ee:master
container_name: chat-app
restart: unless-stopped
env_file: .env
environment:
- MONGO_URI=mongodb://$MONGO_USERNAME:$MONGO_PASSWORD@db:$MONGO_PORT/admin?authSource=admin
ports:
- "8914:3001"
networks:
- app-network

MONGO_USERNAME=mongo
MONGO_PASSWORD=wwww123
MONGO_PORT=27017
MONGO_DB_NAME=test
CHAT_LINK_DOMAIN=http://123.45.678.9:8914
IMAGE_BB_API_KEY=123

should be trivial.
