Did you manage to fix this? Stuck with the same issue.

Here's the fix.
Enable websockets by adding these 2 headers in the NAS reverse proxy settings.

Or below if you are running it on a docker container with caddy, nginx or something else.

        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_read_timeout 86400; //optional
