[ipad] IOS 10 Won't connect to Google or Yahoo?

[ehartley7]

Hi,

 

Having just updated one of our iPads to IOS 10 as a bit of a test I've discovered that Safari won't connect to Google or Yahoo, has any one had this problem and more importantly got a solution please?

 

Here's a bit of detail:

We are part of YHGFL Network and filtering is via their proxy.yhgfl.net:3128 which is configured manually on the devices.

IOS 9.3.5 device works as normal

IOS 10.0.2 Device will connect to bing and a number of other sites including some https: sites ok , but not Google.com.

There are no errors seen, safari just goes straight back to the page you have come from.

 

When the device is taken to an unfiltered/normal/home Wi-Fi network everything works as it should.

 

I'm thinking it must be something to do with the YHGFL proxy certificate, but as it's just started following the upgrade and I'm getting no error message it's not very helpful.

 

Many thanks,

 

Eddy

Also on YHGFL and having no issues with iPads here.

I had to connect to our guest wireless, then revert back to normal one to get working again. On-site proxy here but seems irrelevant. Edited October 14, 2016 by ITGURU

The solution to this was to reinstall the "filtering.crt" which was provided by yhgfl.

 

This allows the the ipads to trust proxy.yhgfl.net when accessing https sites via the proxy.

 

If this cert was missing on the ios 9 it would produce an certificate error. On IOS 10 the page just fails to load with no error.

 

Why the cert was lost doing the IOS upgrade is unknown.
