I have landscape self hosted running on Ubuntu 22.04. I can't get the landscape client connect. The landscape client is installed in Ubuntu Core as a snap.

What should I do?

sudo cp /etc/ssl/certs/landscape_server.pem ~/server.pem

in ubuntu core

sudo landscape-client.config --account-name standalone --url https://ubuntu/message-system --ping-url http://ubuntu/ping --computer-title "node-0" --ssl-public-key ./server.pem

```
