VPN fails every time

VPN fails to activate for the last several weeks. Did a total reinstall - same thing.  

I have had this problem using Vodafone Ireland hotspot and Eir broadband for over a year.

These are my available networks but I have tested the same laptop on 4 other networks - all work.

So Norton need to identify the block. Its clearly not the laptop settings as these work on the other 4 networks.
