Cisco vpn client getting 433 error12/4/2023 ![]() However if the upgrade went through already, here’s what you can do to help mitigate these issues. By removing both the Sonicwall and Cisco VPN software first, I had zero issues with it working properly afterwards. I have now upgraded three different systems to 1511. I would highly advise you remove the Cisco VPN client and Sonic Global client software prior to installing build 1511. I’m getting a lot of feedback about networking being broken after 1511. I’ve been told by several people that the DNE software remains even after the Sonicwall client is removed. If you prefer you can uninstall the Sonicwall client afterwards. Using this method you can now get some more use out of the Cisco VPN client. I tried getting it directly from Citrix and installing it that way but was unsuccessful. What happens is that the Sonicwall client adds the DNE Lightweight filter network client on the machine. Checking the logs shows that it cannot download the key to complete the secure connection. Without installing the Sonicwall client first you will get Error 433 after trying to connect. Full disclosure my systems are clean Windows 10 installs without being upgrades.
