Hello Vincent,
> when connecting to "https://$IP:8081/", I get: > > SSL_ERROR_RX_RECORD_TOO_LONG I think you should try "$IP:8081" instead. The Cuirass web server is not configured to handle HTTPS. You would need to setup an Nginx reverse proxy as here: https://git.savannah.gnu.org/cgit/guix/maintenance.git/. Thanks, Mathieu
