I have worked in IT all my life till retired 7 years ago at 70. I always had to use them to access customer sites for security and have done so ever since to protect/prevent access to my computers. All data going via the VPN is encrypted. This was the first time I have ever had a problem and by changing the the automatic protocol selection to a specific option the problem went away.
I always use the VPN on phone and tablet to prevent hackers accessing them whilst out and connected to local wifi services
