Python Socket Connection refused Errno 111

If you have been running into the following error in Python code, you are not the only one.

ConnectionRefusedError: [Errno 111] Connection refused

According to our experts, this error message occurs due to different reasons. Today, we are going to take a look at these reasons and how to fix the error:

• Incorrect IP Address or Port Number

  One of the most common reasons for the error is an incorrect IP address or port number in our Python code.

  In this case, we have to confirm the IP address and port number in our Python code are accurate and accessible. For example, we can create a socket and mention these values:

  
  

  Here, we create a socket object and use the connect() method to set up a connection with the server. Furthermore, we have to make sure the IP address and port number are correctly defined as a tuple in the connect() method.
• Firewall Rules or Network Configurations

  If our network setup includes firewall rules or configurations that block communication between the client and server, our connection requests may be rejected.

  We can resolve this by inspecting the firewall settings and network configurations. We have to make sure that no rules or configurations are blocking the connection.
• Server is not Listening

  Another key cause of this error is the server’s failure to actively listen for incoming connections on the specified IP address and port.

  In this case, we have to ensure that the server is actively listening for incoming connections on the specified IP address and port. For example:

  
  

  Here, we create a socket object, bind it to the specified IP address and port using the bind() method, and set it to listening mode with the listen() method. The accept() method waits for a client to connect to the server.
