MULTIPLE site down, then up after a few minutes

Hello folks

I have a couple of sites which have been going down a LOT, for a short peroid of time.
I asked the web host, who says

“Sorry that you’re having issues with your websites. We checked and both are live and secure - no errors. The domains are hosted in Cloudflare and not directly to Groove. In this case you will need to contact Cloudflare but we will also escalate this to our Dev team to see what happened on our end.”

I have attached a screenshot from my Telegram bot which says when the sites I asked it to track go down and when back up

www.Man.Academy has been down 7 times today so far, is now 17:30

Any thoughts?

Enjoy your Easter weekend

Many thanks
