Enterprise Application Issue - Linked to recent maintenance ??

Update: We think we have resolved this issue - however having SSL/TLS encryption turned on, i've had to put in some global exclusions for this particular website/enterprise application 

Didn't have to do this before, so either their site has changed or Sophos has 

Hi Simon,

Thanks for following up with the solution you found. When checking the default Threat Protection policy it appears that SSL/TLS decryption of HTTPS websites is turned off when a policy is initially created. 

Do you know if the Threat Protection Policy was changed or updated recently? You can find Audit logs under the "Logs & Reports" menu if needed. 

If you have similar SSL/TLS decryption enabled on a firewall appliance upstream on the network, enabling this protection on the endpoint may not be necessary. 

You can find some further guidance on configuring this feature in the following release announcement.

Not that I am aware of, no policies appear to be changed - hence why this seems strange. TLS/SSL has been enabled for some time, turning it off, made this website work, but turning it back on caused the page to not load properly. We've been using this enterprise app or some time now.. Adding in the exclusions worked fine though.
