Although a VPN client, Cisco AnyConnect isn’t your regular privacy-protection security tool. In fact, this service was developed to help remote workers access the enterprise network and share company resources in a safe, secure manner.

How to fix Cisco AnyConnect’s connection error?

1. Restart your PC

Restarting not only your PC, but also the app itself, your router, and possibly your modem too can have quite the effect in this situation. It’s well-known that your PC builds upon on cached data, but so does your router. Thus, giving them a chance to refresh their internal configuration, discard old, outdated data, and acquire new one might work wonders. There’s a good reason why restarting is the first suggestion of most customer support agents. Furthermore, you could try uninstalling the AnyConnect VPN client and perform a fresh install. It’s not exactly uncommon for updates to render perfectly functional features unusable.

2. Flush your DNS

  If restarting your PC and router didn’t do the trick, manually forcing your PC to discard old cached DNS and acquire a new set of DNS servers might just be enough to put things back in order.

3. Disable Wi-Fi hotspot

If you have a Wi-Fi hotspot up and running on your PC, it would be wise to turn it off and checking if the problem still persists. Reportedly, this issue occurs more frequently for Windows 7 PC users, but it might’ve slipped on later versions of this operating system, as well.

4. Disable ICS

5. Change adapter settings

6. Check your firewall/antivirus settings

Some users reported that certain antivirus software solutions block some programs by default. Therefore, it’s not enough to leave the program (Cisco AnyConnect) as it is. What you’ll need to do is open the antivirus program and add the VPN to a trusted list.

Final thoughts on fixing VPNs failing to establish connections

All things considered, if you’re having a difficult time getting your VPN to establish a connection, you might want to try troubleshooting the issue manually. More often than not, the situation fixes itself. However, sometimes you might need to step into action and perform certain steps such as restarting your PC, clearing your cache, flushing your DNS, or even disabling Windows services temporarily.
