Software is Preventing Firefox From Safely Connecting to This Site

Sophos User1175

hi all,

every website i go on i get this error - 

Software is Preventing Firefox From Safely Connecting to This Site

www.vodafone.co.uk is most likely a safe site, but a secure connection could not be established. This issue is caused by Sophos Endpoint RSA Root, which is either software on your computer or your network.

ive made sure "enable DNS over HTTPS" is disabled ie unchecked

but im still getting the error on every website i try to go on

any help please,

thanks,

rob

    Do you have any additional details on what error is displayed? Could it be "SEC_ERROR_UNKNOWN_ISSUER"? 

    The endpoint is also able to perform TLS/SSL decryption of HTTPS websites. I suggest checking if this is enabled in your Threat Protection Policy. This will remain disabled if you have "Use recommended settings" checked.
