Just sharing a this specific quirk in case it might help someone.
TLDR: "fix" - changed WSL2 networking mode to `Mirrored`.
+ also worth checking hosts file - if `127.0.0.1 localhost` is commented out - splice/bridge does not work (for me) too
Rest of the post - story/some tech details:
Wut happened:
So, I've opened splice and bridge today only to see them not being able to talk to each other. Reinstall/clean-whatever did not work... sadge
Backtracking all the bs I did to my PC recently made me think about them ports/nat.
- ran (as admin) `net stop winnat`
- started splice, then daw with bridge - it works, huh?
What (I think) actually happens:
- splice tries to bind to ports areund ~54000 range
- but Windows Port Exclusion happens - os 'hijacks' port ranges for WSL2/Hyper-V before splice can bind to them. Switching WSL to mirrored mode or using net stop winnat releases these 'hostage' ports and restores the connection.
P.S. not really a network person, please, don't take tech details at face value and correct me, if I got it wrong.
