Is your SSL certificate registered for https://www.gamebeta.co.uk or for https://gamebeta.co.uk (no www)?
Please check your SSL cert confirmation email(s) for these configurations as the www or non-www will make a huge difference.
Whatever the cert is registered for (www or non-www) that is the URL you need to use for https://

If there are no mistakes then I suggest you contact your host again and check if they actually installed the cert correctly.
