SSL Certificate failure on iPhones, iOS10.2.

kaikieferle

Hello; This one seems tricky.

 

When iPhone 6 or later users running the latest iOS try to access their imap.gmail.com or imap.shaw.ca personal accounts they are getting a 'could not verify server' error. It appears the imap servers don't trust the certificate provided by Sophos.

 

Anyone else experienced this? It's only on the iPhone ( my android device works fine ).

 

More information:

We are not using the WAP protection services on the XG210 firewall we have.

It's only happening when... iPhone 6 or later, connected to our wifi access points (which are just plugged into our network), trying to access imap mail servers like imap.gmail.com or imap.shaw.ca.

I've attached screen shots of the details of the error message. I'm sorry, I'm not very good at interpreting them.

    kaikieferle,

    We are not able to see the screenshot. Anyway if you enabled the HTTPS scanning on the firewall rules, you will need to import the certificate on your iPhone. I imported by accessing the XG > Certificate > download Certificate.

    From there, I am not having any issue with email on my iPhone (6s updated to latest firmware).

    Let us know.

    Hi,

    your screen shot says it all, the XG certificate is not trusted.

    I ended up not using mail scanning, just a seperate rule for imap/s to allow iOS devices to receive mail.

    I must have another go at this under 12.1.2.

    Update. I installed the certificate again and like you failure. I deleted the mail account and recreated it which then allowed me to trust the failing certificate. Now to try this on the iPad.

    Further update: while mail now works without errors, I broke a number of websites because of https scanning. Not sure why because the the same websites work on the MBP through the same firewall rule. More work with certificates on the iPhone required before I complete the move.
