We need to retire some old VPN servers which are going end of life in April. A replacement VPN server is already available, and switching over to it just requires

  1. Update your OpenVPN software to the latest version
  2. Update the OpenVPN configuration file on your device

Do I need to update my configuration?

Start up the VPN on your device and go to to find out.

  • If you are told "You are using an out of date VPN configuration file", please follow the instructions in the next section of this webpage.
  • If you are told "You are not using an out of date VPN configuration file", you need take no further action
  • If you are told "You are not on the Chemistry VPN", please make you sure are connected and reload the test webpage.

I need to update; what should I do?

Before updating, we recommend that you download the latest version of the OpenVPN software, because the new configuration file contains some options that do not work in old software versions. Pleaes follow the relevant instructions from the list below to both install the latest software and download an up-to-date configuration file.


If you are not able to connect after updating your configuration, please see our VPN troubleshooting page.

Can I just download a new configuration file?
