You should not access the db via 127.0.01. That's basically the same question as I ask what's your address, and you told me you told me localhost.

Hey @guhao17! I'm here to help you with any bugs, questions, or contributions you have for VANNA.AI. I'm a bot designed to assist you while waiting for a human maintainer. Let's tackle this issue together!

To resolve the error "Can't connect to MySQL server on '127.0.0.1' ([Errno 111] Connection refused)" when using the Dify tool with your MySQL database configuration, you need to ensure that the MySQL server address is correctly configured. According to the provided document:

127.0.0.1 is the internal address of the container. Dify's configured server address needs to be the host's local network IP address.

This means you should replace 127.0.0.1 with the actual IP address of your host machine. Here’s how you can do it:

  1. Find the local network IP address of your host machine. You can typically find this by running ifconfig or ip a on Linux, ipconfig on Windows, or checking your network settings on macOS.
  2. Update your MySQL configuration in the Dify tool to use this IP address instead of 127.0.0.1.

For example, if your host machine's IP address is 192.168.1.100, update your MySQL configuration to:

MYSQL_HOST: 192.168.1.100

Additionally, if you are using Docker to deploy Dify, you may need to use host.docker.internal to refer to the host machine from within the Docker container. Update your MySQL configuration to:

MYSQL_HOST: host.docker.internal

This should resolve the connection issue [1].
