My simonplant.co.uk 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 .`simonplant.co.uk` it redirects to `autodiscover.simonplant.co.uk`

Ive been directed to this article and instructions but can't find correct URL to use or what setting I need to change to. `https://developers.cloudflare.com/speed/optimization/other/mobile-redirect/`

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 www.photographyart.simonplant.co.uk. Any chance this has caused a conflict?

Anyway that site is all working fine.
Regards Simon
