VPN Error 942

Encountering the VPN error 942 can hinder your secure internet journey. But don’t worry.

I have working solutions for the error. I’ll help you resolve it in a straightforward and detailed manner. Let’s get right to it.

What is VPN Error 942?

VPN error 942 occurs when authentication settings between your device and the VPN do not match. 

You’ll get this message: The connection could not be established because the authentication method used by your connection profile is not permitted for use by an access policy configured on the RAS/VPN server.

In simpler terms, your VPN tells you it’s having trouble verifying your login details because of a settings mismatch.

You can fix this issue by:

  • Allowing Microsoft CHAP Version 2 (MS-CHAP v2)
  • Updating your VPN application.
  • Clearing DNS.
  • Using an alternative VPN service.

Below is a detailed step-by-step guide for each fix:

1. Allow Microsoft CHAP Version 2 (MS-CHAP v2)

  2. In the Command Prompt, type ‘ipconfig /flushdns’ then hit Enter.

  4. Open Terminal.
  5. Enter these commands in the Terminal window: sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder.
  6. Press the enter button, then add your admin password.
  7. Hit “Enter.”

Congratulations if this fix worked for your computer. I still have more fixes if this didn’t solve the error.

3. Update Your VPN Application

An outdated VPN app could be another reason you are getting the error. Most services always notify users on their app to update to the latest version. For ExpressVPN, you simply tap on the update button.

Updating VPN app

Alternatively, you can download a new app on the website. To do this:

  1. Uninstall the app you already have on your device.
  2. Go to the official website and tap “Download VPN.” Select a compatible app to install then launch it on your device.

You can use the same procedure for your Mac device.

Once you have an updated version, you should be able to log in without issues but I still have another fix.

Consider an alternative VPN such as CyberGhost VPN if none of the fixes work. Your connection will be stable thanks to its huge network of 11,000 servers.

Using this VPN is as easy as it gets:
