I bet this is an SNI issue when using HTTPS. Before you set up Cloudflare, were you using HTTPS?

Yes! I used HTTPS before Cloudflare installation. Any other ideas?

So it most likely is an SNI issue. Most Cloudflare certificates require SNI-compatible browsers. You’d have to check with Support for ways to fix this. There was a long discussion in another thread that wasn’t able to resolve an SNI issue:

Hi all! I have the same issue with SSL when my website doesn’t work on (Chrome) Windows XP. I’ve already read all your thoughts and as far as I understand there is no solution to fix, right?
Please assist.

As far as I know the Business plan supports it, but can’t really confirm and the support for SNI is extremely high.

Also Chrome on XP supports SNI if updated.
