stanza.co - Cannot Verify Server Identity on iPhone

This started happening to me this afternoon too. At first I thought it may have been tied to an email account, and I deleted and re-added the account. But I recognized stanza.co is used for a few of the sports calendars I subscribe to. After reading through the replies here, I deleted those calendars, and the message has disappeared and hasn’t come back.

Same. I had calendar subscriptions for NHL/NFL and a local AAA baseball team all from stanza.co. I deleted those calendars and the alerts stopped popping up.

Go to your calendar icon and open it and at the bottom of the screen it will say calendar. Click that and scroll down to you subscribed events and delete from there.

My issue was connected to the New England Patriots calendar I had.

Not sure if it’s just Patriots calendars had this issue of it it was all NFL teams calendars.

But, REMOVE/DELETE it and you should be okay.

I posted this week about the same Stanza.co popup after I bought a ticket for an event and I was asked if I wanted to add it to my calendar. I said yes but then the popups started. I couldn’t delete the event because it wasn’t there. It did not occur to me that this problem was also connected to my sports calendars until I read jeffh29’s post about checking the URL.Thank you

Jeff, I did find that stanza URL and had to delete my Warriors and 49er schedules which completely solved the problem. I am so glad I was able to avoid a hard reset on my iPhone 15.

I deleted National U.S. women’s soccer from my calendar thanks!

I found it in my Shared Calendars under the Starbucks Holiday Calendar…so I deleted that calendar…

My wife was getting the Stanza.co message as well. We investigated it and found that the Stanza.co server was connected to the NBA-Warriors calendar. She deleted the calendar from her phone.

Thank you THANK YOU AtLastjh47. You were spot-on with where to go to correct this problem. You need to go into the calendar app from Home Screen. One additional note is that I use a different calendar app than the Apple calendar so if you have more than one calendar app, you need to go into those to remove (or just do it in the Apple calendar and it should replicate this deletion in the other app.). In my case, I use Fantastical and I'd get the error whenever I launched Fantastical. Removing the NFL calendar I had listed in there fixed the issue.

Mine was some Starbucks Holiday calendar. Just check all your calendars. I found it directly in the calendar app and not settings.

This same problem happened to me yesterday after I bought a ticket for an event. Then it asked if I wanted to add it to my wallet and calendar. I said yes to both. It did NOT get added to my calendar but a pop up kept coming up everywhere I tried to go. I could not delete event because it wasn’t added. I could not unsubscribe, I could not get rid of it with a shut down. Support wanted me to do a hard reset which is so drastic. I decided to look at my pass which did go into my Apple wallet. I just removed the pass and that resolved my problem so far. Thought it might be helpful to others.

the suggestion to go into the Calendar app was helpful. I didn’t download any calendars so was thinking this solution didn’t apply to me. I found three links there- not quite sure what they were- but deleted them and no longer have the pop up message. So follow the instructions regarding going into the Calendar app

Found it! It was my NFL team calendar. I deleted it and we’ll see if it stops. So, I guess the Eagles screwed me one last time this year. LOL

I had this same message and it was from an old NFL KC Chiefs subscribed schedule calendar. I unsubscribed from the calendar.

Started happening to me today too. Turned out to be football calendars that were expired. I deleted them and haven’t received the pop ups further. Thanks for the info.
