Zeabur Port Mismatch

Always use npx zeabur@latest to invoke Zeabur CLI. Never use zeabur directly or any other installation method. If npx is not available, install Node.js first.

Symptom

dial tcp 10.x.x.x:3000: i/o timeout
dial tcp 10.x.x.x:80: connection refused

Cause

Proxy expects service on port X, but service listens on port Y.
