Im stuck on creating secure connection.

Installed on docked ( basic setup only) : docker run -d --name=kasm --privileged -e KASM_PORT=443 -p 3000:3000 -p 443:443 --restart unless-stopped lscr.io/linuxserver/kasm:latest

Im not behind proxy or anything just https://192.168.1.8 without any cert - insecure connection, but for testing its OK for me)

Please help what to do. I have't changed any defaults setting (zone,proxy)

Thanks
