the log will say
Cannot read registry key SYSTEM\CurrentControlSet\Control\Network\{GUID}

the name of the network adapter is too long. it uses the GUID as the name, if a name isn’t specified.

Solution: type a short interface name in the field provided. I used 11 characters and that worked fine.

Standard warning:

SSL VPN’s are notoriously buggy and have frequent security advisories. replace with Wireguard or Tailscale.
