The machine node connection is automatically closed after startup

[wang-qijia]

What's wrong?

After starting alloy for 1 second, the console of the machine node is automatically closed.

Steps to reproduce

1. Start ./alloy-linux-amd64 run cfg.river --server.http.listen-addr=0.0.0.0:8802
2. The console automatically closes the connection and the machine node needs to be restarted to recover
