Thanks for the PR. I will look into it at some point this week and get it merged.   For Nginx and websockets, you need to ensure you have set "proxy_http_version  1.1;" I cant say that i have proxied this UI before, but at a guess I suspect this would work:   location / { proxy_pass http://127.0.0.1:32123/; proxy_http_version 1.1; proxy_set_header Host $host:$server_port; }
