The tcp tunnels aren't something that is officially supported cross-platform. Use the default QUIC instead

tcp tunnels only available on Mac?

[doronz88]

even not on mac. i don't know of a rule of thumb where they work.
they do on all my workstations (even windows/linux) and users have reported otherwise so dunno
feel free to submit a PR to fix that
