Yes I see this error and this error is normal when you use Cloudflare.
I see that you are using Cloudflare.
No worries, what you need to do is to disable force https in cloudflare.
What actually happening is Your main website is redirecting to https and clashing with cloudflare.
If you are using wordpress, download Flexible Cloudflare SSL plugin after deactivating cloudflare for a moment, and then reactivate it to get no worries.
Also make your internal URLs non-https because cloudflare will do the work.
Any more help needed, I am just a message away.
