python - 运行 Flask 脚本时如何修复 OSError

Question

在 localhost 中运行 Flask 脚本时，我尝试从同一本地网络中的另一台设备访问网页。虽然我可以查看网页，但我经常注意到这个错误突然弹出，在我的控制台中我的 IP 附近出现随机数，导致 OSError 并拒绝我以后对 Flask 服务器的请求。

Exception happened during processing of request from ('192.168.0.4', 41252)

据我所知，我对错误中的套接字或其他东西一无所知。在我只是将 HTML 模板渲染为响应之后，如何阻止此类错误的发生？

编辑：

我在这里添加了我的 Flask 脚本的一部分，我仍然从中得到错误。当我尝试从网络中连接的其他设备访问我的网页时，再次出现错误

from flask import *

app = Flask(__name__)

@app.route('/')
def index():
    return render_template("home.html")


@app.route('/download')
def downloads():
    return render_template("downloads.html")


if __name__ == '__main__':
    app.run(host="0.0.0.0", port=5000 , debug = True)

这次我也得到了类似的错误如下
