How to remove test-.stanza.co from my iPhone?

I actually fixed the issue by following the solution in this guide: Fix Cannot Verify Server Identity on iPhone which is to remove the subscribed calendar mine was caused by a subscription to a sports calendar, like NBA or football, which was using stanza really happy to have gotten rid of this annoying popup! 

UPDATE: I finally found the little bugger. It wasn’t in the calendar section of active calendars. And since I didn’t subscribe to any sports team calendars, I wasn’t finding what I needed. I found that it was my running app, Nike causing the issue. The app had automatically added a “subscribed” calendar to settings. Once I deleted the subscribed calendar from settings, the pop up stopped. The Nike app is still on my phone but I have not tried to use it since deleting the calendar.

Go to >settings

scroll down to click on >calendars

then click on >accounts

and you’ll see the calendars that you have on your phone.

Click into >accounts and scroll down to >subscribed calendars (might be the very last calendar shown).

Open each to see if .stanza.co is in the server name of any of those. If so, delete it.

Hope this helps.

Did not work! The popup continues…

Cannot Verify Server Identity

The identity of "www.stanza.co" cannot be verified.

I deleted every calendar I could and the whole app and that annoying message still comes back.

You are quite welcome, and thank you for the feedback.

Check for subscribed calendars (possibly a sports team)

It worked for me. Thank you. I looked at the subscription details for each calendar and found stanza.co for the NBA calendar I was subscribed to

Me too, its annoying!!! Do you have any solution already to get rid of this?

I’m having the same problem

I bought Nortons to try to fix it but that did not help. Following the advice here, I checked every calendar I subscribe to. The NY Giants calendar was the one with Stanza. I have had it for years - perhaps they “updated” their app?! Goes along with the horrible year they had 🤣

I unsubscribed every calendar I had still getting the message any other options. I also did avast looking for a virus that did not solve anything either.

I found it under my sports calendar. I deleted it. Unfortunately, I have a feeling I will not see any upcoming games or alerts in the future… It’s still beats the annoying pop up!

I deleted 2 sports calendars, one college and one NFL, not getting the pop-up anymore. Both showed the test-stanza.co in the "Subscribed To" section under Subscription Details.
