HTTPS forwarding to test page/SSL hanging

Hi all,

I've added a new domain to CWP and it resolves. However I seem to be having an issue in that the site loads the test page when requesting https://xyz.uk

It loads http as it should.

Secondly I'm trying to install a letsencrypt and on telling it to do so, hangs on installing and then the panel becomes unaccessable.

Any ideas? I've ran out of ideas!

same problem here on a newly installed Server...
