Gmail App - An unexpected error has occured

[Sheridan]

We've got some iPad Airs running IOS 9.02 configured with Apple Configurator to connect to our wifi and install a few Apps.

 

One app is Gmail - which goes through the normal authentication process and on the first screen, where you have the two options for Go to Inbox or Start Tour, it simply says 'An unexpected error has occured. Please try later'

 

Its happening on all of them, and looking at the unauthenticated proxy logs I can see normal access to mail.google.com, accounts.google.com etc going through.

 

I'm baffled as to what else would be blocking this, or what is causing the error? I'm open to any suggestions!

Not looking good. Gmail + iOS + Smoothwall = game over!

 

Docs/Sheets/Drive all work fine. I guess Gmail is another one to add to the list of things that ignore a proxy.

Did you ever have any luck with this? We've rolled outsome iPads and are having the same issue.

Are you using Smoothwall or some other HTTPS inspection based filtering? Thats what killed it on our ipads - we had to change the rules to let them avoid https inspection for the gmail apps.

We are (through our LA), I've been pretty sure this is the problem for a while, but they haven't been able to fix it yet. Was just hoping there might be a way around.

That was the only way we could fix it - as the Gmail App, and also Chrome don't work with MITM inspection. We could direct staff to use Safari for browsing but using the Gmail app was so much easier for their email that we had to modify our smoothwall to sort this out.

 

With you having filtering through the LA I'm not sure how they'd do it, unless they can do it for a specific ip range.
