cannot verify server identity

My iPhone keeps getting a pop-up that says "Cannot Verify Server Identity". I've seen several answers about fixing this if it's related to mail. But this message says, "The identity of 'calendarclubs.bluesombrero.com' cannot be verified."

Checking the Details option has not helped.

Any ideas, friends? Thanks!

iPhone 6, iOS 12

This has been happening to me and my mom for the last month at least, too! I think I finally found the solution, although I haven’t deleted it yet to see if the pop-ups stop, but I think they will.

First, open up your settings app. And then scroll down until you get to calendar. Open that up and review your accounts. Mine has 5, one of which is listed as a Subscribed Calendar named Storm. I clicked for more details and that is where I found the server to that calendar is named calendarclubs.bluesombrero.com. I have no idea what that means or where it came from, but I deleted it! Hope this stops my pop-ups and yours!
