Hi,
Curious if anyone can provide some background on some consistent/persistent SSLVPN errors we are seeing in the log on our RV345P
Before we start, Firmware is: 1.0.03.22
Smart Software licensing is "Registered" & "Activated"
We do have a Site-to-Site VPN between two RV345Ps
We had enabled the SSLVPN a month or so ago and then disabled when we say a bunch of attempted connections that were not from us (ie we had one laptop with Anyconnect set up for testing and it was not being used).
Have been having issues with the RV345P at our other site where 3-4x daily it loses WAN connectivity with the cable modem in bridge mode that it is connected to (will post that issue in a separate post) which got us looking into root cause and taking a look a the logs.
Here are the errors we are seeing, is this just someone doing a scan and attempting to connect via SSLVPN?
Is there anything configuration wise we can do on the RV345P to prevent these errors?
Any context/guidance would be appreciated.

Original post had longer output of logs but seems it was flagged on the message board system for some reason.
Above are just chunks of the different error sequences we are observing and I have attached the text file of the logs to the post.
