Cisco QuickVPN Client Error: Server's certificate doesn't exist on your local computer. Do you want to quit this connection?

If the above error happens run the following command from an elevated command prompt:

  1. Navigate to: C:\Program Files (x86)\Cisco Small Business\QuickVPN Client>
  2. openssl.exe s_client -showcerts -connect 99.99.99.99:443 >c:\temp\cert.pem
    • Where 99.99.99.99 is your WAN IP.
    • Make sure that there is a Temp folder under C:\
  3. Copy the cert.pem file from C:\Temp to the QuickVPN Client folder.
  4. Click Yes and through the UAC prompts if required.
  5. Close and re-open the QuickVPN Client
  6. Connect.

    In my experience, cisco QuickVPN is a nightmare that barely works. I got mine working for about a day but then required constant troubleshooting. I opted out of QuickVPN and set up the PPTP Purevpn server on the firewall router and was able to connect easily with Windows' built in VPN. This was for an RV042 and only allowed for 5 usernames to VPN with, not sure on the limit of the RV180, but I would definitely give it a shot.
