Hi

Our company has resently renewed our external certifcate for Exchange active sync. The certificate is SHA2 signed.

From that day Nokia C5,E71 and E72 models stopped syncing.

I belive that it has to do with the SHA2 signing algoritm, and I just want to get that confirmed or confirmation that it isn´t that that causes the communication issues.

Thanks in advance

    Hi,

    Just to confirm that installing the .sis file fixed all my Gmail and Google Apps mail connectivity problems. 

    And I can now connect to google sites, including web gmail, google search results and pages like Wikipedia using the Opera Mini Browser. Previously the Opera browser said it had connectivity issues on all those pages.

    He there

    I faced recently (about two weeks ago) the same problem. All of a sudden the default email solution in my phone (E71) stopped working. Installed email programs, like profimail, nokia mail, mfe, doesn't work too with gmail. Besides the default browser in the phone doesn't open secured page with access to gmail, unlike opera.

    Could you advise me how to fix this problem if this possible?

    I read above that network improvement sis (which doesn’t run on my phone) should be installed and all the certificates collected here http://www.traud.de/ta/. Do I really need all of them?

    Regards

    Nic

    the default E-mail solution in my phone (E71) stopped working [with Gmail]

    In your case, the certificates do not help. You would need that SIS. Since

    • July 2015, Google Gmail
    • January 2016, Outlook.com (former Hotmail)

    switched to SHA-2(56) and disconnected millions of devices, although alternatives like ‘ECDSA/SHA-2 + RSA/SHA-1’ do exist. Phone models like

    • Nokia E51,
    • Nokia E71, or
    • Nokia E90 Communicator

    are based on Symbian/S60 3rd Edition Feature Pack 1 and do neither support SHA-2 nor this SIS. I am not aware of any workaround except to

    A) use a proxy based Internet browser, like Opera Mini

    B) change to a newer phone, like the Nokia E72 or Nokia E6

    If you use additional E-mail providers which do not work anymore either, please, name them. Then, I double-check whether it is the same cause. If the cause is different, there could be a workaround.
