HI. I can establish SSL VPN connection for my RV340.
I get the following errors.
Anyone would can help me?

Honestly, these failed VPN connection attempts have NO binding to Cisco AnyConnect SW. Sorry Cisco guys, but tell me a reason or evidence what do you have for this opinion.
Based on firewall logs, I can see hundreds of similar attempts per month in times when evidently no VPN connection was initiated from my side. Also, the frequency of these attempts (5-10 within a few seconds) leads to the conclusion that these attempts are 3rd party common scan. As the firewall doesn't log directly the source IP addresses, I can only speculate, that a "number" in brackets is a HEX representation of DEC IP addresses (YY.YY.YY.YY HEX -> XXX.XXX.XXX.XXX DEC). If so, these IP address sources are from China (China Unicom, etc.).
I assume in your case somebody tries to connect to your router.
In the case below the SSL VPN feature on the RV340 when enabled allows connection from a client using Cisco Anyconnect Secure Mobility Client. That is the only function it has. Martin asks for help how to make that work.
I understand he tries to connect from his client and gets an error in the RV340.
