Sophos Enpoint Central couldn't install with https filtering active

Hello all,

 

I'm having an issue into a customer office. I have a Sophos UTM 9 with https decrypt and scan active. When I want to install Sophos Endpoint Central, many connections to https://52.16.36.153/ or other ip (https://52.213.87.124/, https://54.77.141.191/) who are protected by SSL certificate *.prod.hydra.sophos.com

Same constatation with https://87.248.214.67/ or https://178.79.251.10/ who are protected by ssl certificate downloads.sophos.com

 

So the certificate doesn't match to the url, and UTM deny connections.

 

How can i install Sophos Endpoint Central with https scanning active ?

 

Best regards,

Benoit

    You may need to exclude in HTTPS scanning exceptions,

  • There is also an issue with mismatched certificates. Our clients are using the following preferred server:

    https://foo.example.sophos.com/

    However, the web server is using a wildcard cert for *.prod.hydra.sophos.com

    This has halted automated installs of Windows since we have to manually intervene by opening the above URL in IE and accepting the certificate. Adding the URL or *.sophos.com to our trusted sites list does not make it go away. Previously installed clients are getting policy from an update server on our LAN but new installs are failing or taking considerably longer than usual to complete -- often with manual intervention as above but then still waiting a long time for the encryption and other policies to be received. Please advise on whether this is an ongoing issue. I have opened case # 7066879 but only this morning after waiting two days for my SophosID to start working again.
