Check with your VPN provider. It sounds like your VPN might be proxying
SSL traffic, in which case you will need to trust their certificate.
That will allow the proxy on the VPN to intercept your SSL traffic,
perform whatever filtering the organization's policy requires, and then
pass it on to the destination.
Does the same sort of prompt appear when attempting to view a web page
over HTTPS?
If that is what is going on, most likely a self-signed certificate is
being used and you would need to explicitly trust the certificate.
