Problem with iOS WireGuard client

[John]

Your issue sounds similar to mine linked below.  Do you find this
endless failed handshakes to be when you're connected to any network
or just a specific one?  I routinely connect to 4 networks in my
travels and only 1 of them causes the problem.

If I disconnect/reconnect the WireGuard tunnel, the handshakes succeed, and traffic starts flowing normally again.

This happens regardless of what network my iOS device (i.e., my phone) is on.  Sometimes when the IPv6 address is shown and I refresh the page a few times (over the span of a few seconds), it switches to show the endpoint's IPv4 address.
