VPNs have become rather essential software these days, with internet privacy being compromised. There are a lot of good VPN clients to choose from, so there’s no excuse for not protecting yourself online.

However, VPN software doesn’t always play ball with your internet connection. In this article, we’re looking at ExpressVPN’s unexpected errors when connecting to a server and sharing a few solutions you can take to fix the ExpressVPN unexpected error

Update your PC 

The first thing you should do is to update your PC. Updating your PC will, in most cases, update your drivers and fix any issues in the process.

Check your antivirus

Although a bit of a far shot, you should check your antivirus to see if it restricts your VPN client’s access. This can happen for several reasons, but if something fishy shows up in your antivirus, there could be malware present on your machine that could be causing the ExpressVPN unexpected error.

Also, if you’ve got more than one antivirus program on your PC, try disabling all but one. Multiple antivirus programs can often cause conflicts that can cause problems with your VPN client.

Use command prompt to flush DNS

Incorrect DNS settings can and will mess up your VPN configurations. Revert them to the default settings to see if that solves your problem. Here’s how. 

Step 1: Press Windows key + R and type cmd. Then hit enter.

If the above command doesn’t help, try entering these commands in the Command Prompt one at a time.

netsh winsock reset
netsh int ip reset

If you suspect an issue with your router’s DHCP assignment, use these commands to release your old IP and request a new one. 

ipconfig /release
ipconfig /renew

Use the following commands to reset your network stack if this doesn’t work.

nbtstat -R
nbtstat -RR
netsh int ip reset C:\resetlog.txt
netsh winsock reset

Now try restarting your PC and running ExpressVPN again to see if that solved your problem.

Automatically register your IP

If your DNS settings aren’t the problem, your IP registration could be causing the issue.

Step 2: Enable the Automatically register my IP address setting and click the Register my IP address button.
