It doesn't appear to be possible to connect to the RV340 device via Anyconnect using SSL VPN without the Security Warning: Untrusted Server Certificate! message.
I have tried:
1. Exporting from IIS to PFX file and importing this file - this creates two entries in the certificates table.
2. Downloading the CRT file from GoDaddy and importing the certificate
3. Creating a new certificate through Comodo and importing the CRT files (I've tried all three in the ZIP file)

I've tried applying all the certificates without any success:

Can anyone connect to an RV series device via Anyconnect using SSL VPN without getting the warning message?
