OSError: [Errno 98] 地址已用于启动 TCP 服务器服务

如何解决OSError: [Errno 98] 地址已用于启动 TCP 服务器服务

我有上述错误。我正在尝试为 ngrok 隧道向世界公开的网络服务器编码，并从 Github 接收 webhook。无论我从端点收到什么，我都会转移到下一个 TCP 线程。无论我尝试启动，在重新启动 agin 或更改端口号之前等待 5 分钟，我都会遇到相同的错误。我的代码如下

from flask import Flask,request,Response
import socket
import threading  
import json
from pyngrok import ngrok


#tcp server
TCP_IP = '127.0.0.1'
TCP_PORT = 13370
BUFFER_SIZE  = 2048

def start_ngrok():
    url = ngrok.connect(5000).public_url
    print(' * Tunnel URL:',url)

def launchServer():
    print("TCP thread started")
    s = socket.socket(socket.AF_INET,socket.soCK_STREAM)
    print("Socket successfully created")
    print(s)
    s.setsockopt(socket.soL_SOCKET,socket.so_REUSEADDR,1)

    s.bind((TCP_IP,TCP_PORT))
    s.listen(10)

    while True:
        print('waiting for a connection')
        conn,addr = s.accept()
        try:
            print(sys.stderr + 'client connected:' + addr)
            while True:
                data = conn.recv(BUFFER_SIZE )
                # print >>sys.stderr,'received "%s"' % data
                if data:
                    conn.sendall(data)
                else:
                    break
        finally:
            conn.close()

app = Flask(__name__)

# route deFinition
@app.route('/<webhookAddr>',methods=['POST'])
def response(webhookAddr):

   if webhookAddr == 'getGithub':
      # data = json.loads(request.data)
      print(request.json)
      return Response(status=200)

  else:
      return Response(status=200)


if __name__ == '__main__':
   t1 = threading.Thread(target=launchServer)
   t1.daemon = True
   t1.start()

   t2 = threading.Thread(target=start_ngrok)
   t2.daemon = True
   t2.start()

   app.run(debug=True)

那么最终导致错误的原因是什么
