Good info actually; perhaps it's the IPv6 requests.  If you set IPv6
method to "ignore" in NetworkManager does that make things work?

Or with nmcli, something like:

nmcli con mod <name> ipv6.method ignore

That should cause NM to stop requesting an IPV4V6 context.  But also,
what version of NetworkManager do you have?  Recent versions of NM have
fallback logic to try only IPV4 if V4V6 fails.
