"cannot verify server identity of "carddav.address.yahoo.com""

[fanboy05]

I keep getting this message on my screen and I dont know why. I do not have a yahoo address like that at all.
it asks if I would like to continue anyway, I say cancel, because I didnt ask to go there.
Does anyone know why this keeps popping up?

I am also having this problem. My yahoo contacts are not syncing to my phone. Does anyone know if the yahoo server is down? I'm running an iPhone 4 on ios 5.0.1. Thanks.

I had the same error and...

I also received a message that said cannot connect to caldev. Funny thing is I have never setup any account to point to a caldev address since caldev is for calendars. My contacts have been working flawlessly for the last 6 months even after an iOS 5 upgrade until this week.

I did some more checking and it looks as though the carddav.address.yahoo.com url is pointing to caldav.calendar.yahoo.com which is Yahoo's calendar server.

You can verify by entering either address in your web browser and it always comes up to the calendar page. I verified this at multiple sites to make sure it was not my isp.

I also did a tracert on both addresses and the endpoint address for both although different still point to the calendar when I enter them in a web browser.

tracert carddav.address.yahoo.com
final result: cardgate01.cal.vip.ac4.yahoo.com (216.109.126.235)

Navigate from chrome https://216.109.126.235/
You attempted to reach 216.109.126.246, but instead you actually reached a server identifying itself as caldav.calendar.yahoo.com

tracert caldev.calendar.yahoo.com
final result: calgate01.cal.vip.ac4.yahoo.com (216.109.126.246)

navigate from chrome https://216.109.126.246/
You attempted to reach 216.109.126.246, but instead you actually reached a server identifying itself as caldav.calendar.yahoo.com


I sent this to Yahoo and will see what response I receive.

Allow me to preface my reply by saying that I am NOT tech savy AT ALL!!! I had this same issue yesterday, out of the blue. I read somewhere that it had something to do with entering your yahoo password somewhere. Anyway, may just be coincidence, but last night I logged into yahoo messenger right after I got that message again for the 50th time today. I had to re-enter my password - which I never have to do. After doing that, I have not had the message pop up again at all.

Yahoo Contacts Server Down?

Hi, I also had this problem start Nov 14, 2011. For all who are wondering, if you use Yahoo! Email and tell it to "sync Contacts", they automatically configure the CARDDav server for you. YES, it appears to be FAILING. But this post is the only hint that others are having trouble, with no official word, email from Yahoo! or anything.

cannot verify server identity of "caldav.calendar.yahoo.com"

I am getting a similar message and it just will not stop. It started about a week ago and I don't know what to do about it. This is the exact message:

Cannot verify server identity
Yahoo! cannot verify the identity of
"caldav.calendar.yahoo.com"
Would you like to continue anyway?

Cancel
Details
Continue


I understand that this has something to do with yahoo calendars, which I do not and have never used. If anyone knows how to fix this I would appreciate any help you can provide. Thanks.

Solution!

Make sure your Date and Time are set up correctly! If they are not current, then you WILL get errors. This happened to me. And I eventually realized my date and time for set to 1997 LOL.
