Hi John,
Which VPN you are using now (third party software or Windows build-in function)?
Does WIFI work well when you not through VPN connection?
Uninstall the existing wireless driver and install the latest version from manufacturer website.
Please check if the issue occur in Clean Boot environment.
If the issue persists, please try the following steps:
Check if you could receive reply when ping server.
Check listening port 443 with command line "nestat –ano | findstr 443“ as administrator.
Tick "include Windows logon domain" through Control Panel\Network and Internet\Change adaputer settings\right click VPN network icon\Properties\Options\include Windows logon domain.
Please remember to mark the replies as answers if they help.

I just got a brand new Dell Notebook PC on Dec
Got the same issue that it works with LAN but not WIFI.
AssumeUDPEncapsulationContextOnSendRule does not help.
Using USB WIFI cannot solve this issue.

If you have an intel wifi card, then dell ships with "smartbyte drivers and services", if you have a killer wifi card, then it ships with the Killer Wireless Suite. To get your vpn working, uninstall these types of software. These 3rd party network drivers are supposed to prioritize network traffic to give priority to streaming video or something like that, but they are more trouble than they are worth in my experience. They mess with VPNs.
If you have trouble uninstalling any of these apps, use the Microsoft Install / Uninstall Troubleshooter you can download from microsoft:https://support.microsoft.com/en-in/help/17588/fix-problems-that-block-programs-from-being-installed-or-removed
