Hi

When receiving a picture on Whattsapp Desktop App on Windows 11 i get the following Log entry (ATP500) and the picture is not downloaded:

client finished Receive fatal alert message: desc = 48(unknown_ca) => Block/Reset SSL session!

Certificate is up to date.

Is there a solution for this? Thank you.

    Seems CA is invalid. Do you select the default certificate?
