I'm getting these errors in my Router Log (AC68U running latest Merlin). Anything to worry about or benign? Any adjustment to try?

TLS Error: unknown opcode received from [AF_INET] op=20
TLS Error: Unroutable control packet received from [AF_INET] (si=3 op=P_ACK_V1)
TLS Error: cannot locate HMAC in incoming packet from [AF_INET]
TLS Error: local/remote TLS keys are out of sync: [AF_INET] [2]

Looks like standard port scanning. Expect to see a lot of that as you're using a common port (443).
@eibgrad Nothing that I know of, other than the VPN
Well you can only have one service running on one port, so that will be the VPN.
@ColinTaylor Ok, so it sounds like "nothing to worry about"?
It's more of an annoyance really. Once the bots have seen a response on that port they keep coming back. Then over time more and more bots discover it. Just change to a non-standard port and the messages will disappear.
