Could not listen on public domain name - web page always show: 404 page not found

just hours ago, I followed the doc on section to add the CVAT_HOST to my public domain name(for security reason, i replaced the real domain to MY.HOSTNAME.com) with: export CVAT_HOST=MY.HOSTNAME.com, and then ~/cvat/sudo docker-compse up -d, all works fine, I can access the web from public internet by typing MY.HOSTNAME.com:8080 in browser.

but somehow later, after I played with the port number changing(no luck yet though followed the doc by changing a bit in traefik section in src\docker-compose.yml : --entryPoints.web.address=:8080) and some docker-compose up and down, then web cannot open anymore from public internet by MY.HOSTNAME.com:8080, so I delete all docker images and source, and re-clone repo and re-download docker images again from scratch, now the local host accessing is OK, but, still can not get the web page open again from public domain name, for debug, I used sudo docker-compose up to get more output, you can see the CVAT_HOST is already properly set:
