HTTP connection has closed: c540 - caprover


I'm installing it on caprover, even with active websocket the login and password don't appear, they just stay on the "Waiting for master server..." page. Locally on my notebook, it worked perfectly.

Do I need to put a specific env var for it to work in production?

Start by reproducing the Docker deployment on CapRover and compare it with the working local installation. Use the supplied WebServer log, especially the keep-alive and closed-connection entries, to investigate why the login page remains waiting for the master server. Done means the production deployment displays the login and password fields and the required configuration is documented.
