Sophos not allowing to use certificates in certain webs

Hi Carla,

Thanks for reaching out to the Sophos Community Forum. 

May I ask what web browser you are using? If you are using Firefox, I suggest checking the "Firefox and decryption" section of the following article. 
- SSL/TLS decryption of HTTPS websites

Let me know if you've excluded the site from decryption under the "General Settings > SSL/TLS decryption of HTTPS websites" or if this has only been done from within the Threat Protection Policy.

Hi Qoosh ,

It is not Firefox, it is Edge or Chrome. I already read that Firefox works with its own databases. 

And answering the other question, I have put it as exception of the policy, in the genereal settings and as global exception too, it doesn't work either. 

To resume it, in every exception page that Sophos Central has.

Regards!!

Hi Carla,

Good day.

1. Ensure that the policy gets received on the device once you save it. Open the Sophos endpoint self-help tool on the device -> Policy-> check the latest timestamp for network threat protection and Sophos adapter. 
2. Post upon that, you could clear the browser cache once and then try to browse the site again by relaunching the browser.
3. Also, is the device under EAP? If yes, just for testing, you could remove that from EAP and try the issue.

could it be loading resources from other domains?  Maybe take a look in the Developer tools at the Network tab and enable the domain column.  It might provide some insight.
