解决方案

  1. 90% 成功率 Start server with correct host and port 
    uvicorn app:app --host 0.0.0.0 --port 8000
# Then connect to http://localhost:8000
  2. 80% 成功率 Check firewall and network settings 
    sudo ufw status
# Allow port if needed: sudo ufw allow 8000

无效尝试

常见但无效的做法:

  1. Checking only localhost without specifying port 70% 失败

    Server may be on a different port or bound to 0.0.0.0.

  2. Using wrong protocol (http vs https) 60% 失败

    If server uses SSL, http connections fail.
