Create a self-signed certificate to configure it so that it can be accessed from other hosts via HTTPS.
debian@dlp:~$
systemctl --user start code-server

debian@dlp:~$
systemctl --user stop code-server

# create certificate

debian@dlp:~$
cd ~/.config/code-server

debian@dlp:~/.config/code-server$
openssl ecparam -name prime256v1 -genkey -out server.key

debian@dlp:~/.config/code-server$
openssl req -new -key server.key -out server.csr
