I joined this community while trying to find a solution to (what I think is) a Windows 10 update problem.... I'm hoping to find the magic fix. I'm a retired RF Engineer with 49 years in broadcast television. I'm somewhat computer literate and fairly trainable for the vast world IT knowledge in which I'm still unfamiliar.
I've used a Meraki VPN to connect to various networks I need to access for my work. It's always worked flawlessly - until this W-10 Pro 64b update tripped me up.
I do a lot of volunteer work at our community theater helping with the sound system, microphones and lights.
You may want to check your Win 10 VPN settings - both for sign-in options (if you have username /password set) this will be under Settings>Network & Internet>VPN, as well as the Adapter settings in the network connections section.
Make sure that under the Security Tab that PAP is checked off and no other boxes.
I find that my win 10 changes those on me at will and I always check before connecting
