   This is a WSL2 networking nuance rather than a docs bug. The default 
\`be.conf\` setting \`priority_networks = 127.0.0.1/32\` works for a 
single-host quickstart on most systems but breaks under WSL2 because WSL's 
loopback is namespaced per-distribution and the FE-BE handshake can't reach BE 
through 127.0.0.1.
   
   For WSL2, set \`priority_networks\` in \`be/conf/be.conf\` to the WSL 
interface subnet (typically \`172.16.0.0/12\` or whatever \`ip addr show eth0\` 
reports), then restart the BE. The fact that the mac script works is consistent 
with this — the mac launcher binds to the host-routable interface rather than 
loopback.
   
   The quickstart doc could call out the WSL caveat. If you'd like, I can add a 
"running under WSL" note in a follow-up. Otherwise this can be closed since the 
underlying cause is environment configuration, not a doc error.
