keeps loading 3 dots when accessing the domain

hi,

anyone can help pls..
seeing this meteor_runtime 404 when accessing rocketchat domain and just keeps loading 3 dots.

deployed via docker-compose and using nginx reverse proxy and cloudflare.
also i am able to continue in setup wizard when i just access it thru http://ipaddress.

# Rocket.Chat version
# see:- https://github.com/RocketChat/Rocket.Chat/releases
RELEASE=6.4.5
# MongoDB endpoint (include ?replicaSet= parameter)
#MONGO_URL=mongodb
# MongoDB endpoint to the local database
#MONGO_OPLOG_URL=mongodb
# IP to bind the process to
BIND_IP=127.0.0.1 ## already tried 0.0.0.0 also
# URL used to access your Rocket.Chat instance
ROOT_URL=https://rocketchat.example.com
# Port Rocket.Chat runs on (in-container)
PORT=3000
# Port on the host to bind to
HOST_PORT=3000

### MongoDB configuration
# MongoDB version/image tag
MONGODB_VERSION=5.0.22
# See:- https://hub.docker.com/r/bitnami/mongodb```

Start by reviewing the docker-compose deployment and nginx reverse-proxy configuration, comparing access through the configured domain with direct access by IP address. Done means the domain no longer returns the meteor_runtime 404 and Rocket.Chat completes loading instead of showing three dots.
