hoosty over 3 years ago

Hi,

The weird thing is, its only in firefox, edge works fine.

Do you have a hint for me?

Hi,

There should be a lot of exceptions for Facebook, you might need more. Also check what default tls version each browser is using.

OK, decreasing the maximum TLS Standard helps.

In about:config the value of security.tls.version.max must be 3. It seams that Sophos Scanning is partially incompatible to TLS1.3

Hi,

you can set the minimum tls level in the tls configuration GUI.
