Re: TLSv1.3 is now an approved standard how will D & E series 5.6 Fortigates deal with it?
Nope, can't reach Mozilla, packet capture shows a RST ACK packet sent from the FG to the Client.
I'ts definitely TLS1.3, the policy has no security profiles now, only Deep Inspection, as soon as we switch the policy to certificate inspection everything works normal.
I'll open a support ticket, thanks for pointing me to the right direction.
