There are many benefits that come with using a VPN, but there can sometimes be many headaches as well. One of such annoying issues is Error 429: Unable to resolve server address.

Stop conflicting VPN software running in the background

When Task Manager opens, locate the program’s process, click it and then click End Task below. Now check with the VPN software that you want to use if the issue is still there.

Run the VPN client software as administrator

Uninstall and reinstall the client software

If all else fails, you can try uninstalling the software completely and then reinstalling it. This will solve the problem if the client wasn’t installed properly or has components that have been corrupted.

Call customer support

This is often the last resort. If nothing works, then it’s possible the customer care can help you solve the problem, especially if the issue is related to your account.
