Computers using the Chemistry VPN service need to update their config files by 6th March 2025 in order to ensure they can still connect to the service. You can check if you need an updated config file by turning on the VPN and going to https://apps.ch.cam.ac.uk/vpn/vpn-test/ . Unless you downloaded your VPN config since 6th February 2025, you will need to update.
Detailed instructions for updating
Please follow the relevant instructions from the list below to both install the latest VPN software and install an up-to-date configuration file.
Troubleshooting
If you are not able to connect after updating your configuration, please see our VPN troubleshooting page.
Direct links to the updated config files
Please note that if you're on Windows just importing the config file into OpenVPN will not work as it will put the file into a subfolder of the config folder. Copy the file into C:\Users\<yourusername>\OpenVPN\config by hand instead.
