My gets redirect but only on mobiles https://.autodiscover

Hi Ive suddenly had an issue with my website not loading on mobiles.
I use free version of Cloudflare through my hosts Cloudways.
When I use url .`` it redirects to ``

Ive been directed to this article and instructions but can't find correct URL to use or what setting I need to change to. ``

Ive had to deactivate Cloudflare until I can get some direction which I'm hoping I can find here.

Im interested to find out why this has suddenly become an issue.
I recently purchased 10web plugin with access to Cloudflare premium features for my sub domain Any chance this has caused a conflict?

Anyway that site is all working fine.
Regards Simon
