iOS 9 VPN issues? Downgrade to iOS 8.4.1 for now

“Enterprise and BYOD users beware – upgrading to iOS 9 can break your ability to access VPNs,” Adrian Kingsley-Hughes reports for ZDNet. “The symptoms are pretty straightforward – you upgrade to iOS 9 and are then you find that you are no longer able to connect to some servers over VPN because of failed DNS resolutions.”

“Internal connections to servers from corporate networks are unaffected,” Kingsley-Hughes reports. “The current beta release of iOS 9.1 is also affected.”

“If you’ve upgraded to iOS 9 and you can’t wait for Apple to fix this issue then your only hope is to roll back to iOS 8.4.1. But there’s a catch – you can only do this if you made a backup of your device via iTunes (not iCloud) before carrying out the upgrade,” Kingsley-Hughes reports. “If it has been purged, or you didn’t make a backup before you upgraded, then you can download the applicable file from Apple (links available in full article), but bear in mind that your device will be factory reset if you use this file.”

MacDailyNews Take: Hopefully everyone affected has either backed up to iTunes or can forgo VPN access until Apple issues the fix which will hopefully be coming very soon!


  1. Hmmm. Networking is clearly not Apple’s strongest suit. After the calamitous wifi issues in Yosemite you would hope Apple recruited some networking experts… Unfortunately the Apple of today is very much a consumer business. Real work on Apple gear is becoming less and less viable…

  2. Same here. No issues with Private Internet Access or PureVPN. Upgraded while on vacation so, glad it worked.

    Now, I did do an IPSW restore with backup restore afterwards and not an upgrade (mostly because I clicked on the wrong button! ☺️)… Wonder if that matters here?

  3. ugh. What’s up with Apple and network/internet connections nowadays? I held off upgrading to iOS 8 because of (reported) flaky wifi connectivity. Now this. (although it must be said I don’t need to connect to VPNs all that often. But still…)
