the certificate for this server is invalid

Hi can anyone help?  I get a message "cannot connect to iTunes Store" when selecting App Store on my iPod.  Also if I try iTunes icon, I get "the certificate for this server is invalid.  You might be connecting to a server that is pretending to be "itunes.apple.com" which could put your confidential information at risk"

• The steps I have taken so far, - connected to PC and updated software to iOS 6.1.3 (worked fine on PC)
• Checked WiFi connection (fine)
• Checked other apple products are working fine (yes)
• Checked i am logged into apple id (yes)

Is there anything else I'm missing ??

Thanks aliian

Fix =  the date & time the year was incorrect.

settings>general>date & time>set date & time

Cheers

whoop! thanks, was having this problem too

Yay, thank you, time & date was the problem, set to automatic and now it's fixed

Fantastic, beein tearing my hair out for 2 weeks, that simple, hey Apple folks, take note next time someone asks you!

Worked perfectly!!  Thank you!!

this helped. thanks!

Have you been playing Candy Crush and/or changing the date/time to get extra lives (like I was???!!)  Set the time back to the right time and everything will work again including app store and mobile banking.  Hope that helps ye!

Just go to the date and time and set it to set automatically then it will work. I just fixed mine! Enjoy!

Thanks for the solution. I was a Candy Crush player too. Why is the App Store tied into the internal date on the iPad??? crazy!

worked the instant the date/time was fixed.  Thank you!

Brilliant.....so simple...was trying everything..many thanks

Thanks to those contributing this fix -- had this issue on my son's iPad mini and was going crazy trying to figure it out!!

To answer the question of why this causes an issue: this is part of the standard security features of the internet - when you connect securely to a server (as the i-devices do when accessing itunes), it has an SSL Certificate which has an expiry date on it -- the device checks the certificate to try and make sure you aren't getting duped by an out of date certificate, and if your date is set too far in the future (my son's was in 2019!) then it looks like the expiry date is in the past and it won't let you connect..

Cheers!

Many thanks for some reason my phone go set to 1st Jan 1970, and my phone, network settings etc went havoc! Such a simple fix - although the apple store itself could not fix this!! You are a genius!

Thanks bunches .....totally helped me.  Didn't even notice my son's ipod was 7 hours off and no idea how how many days/years.   The auto time was unchecked.. checking it and rebooting the phone allowed me to connect him to his icloud.  Thanks again
