Hi all. I am trying to run Open edX for development on my Ubuntu 22.04.3 LTS laptop. I am using Python version 3.8.10.

Step 1: I installed the latest version of Tutor using the command `pip install "tutor[full]"` (current version is 16.1.1).

Step 2: I ran the command `tutor images build openedx-dev`. Then I ran the command `tutor dev launch`. While this command is processing, I encountered an error: `ERROR 1130 (HY000): Host '172.19.0.8' is not allowed to connect to this MySQL server`.

Your mysql container is crashing/restarting in an infinite loop. What’s the output of `docker ps | grep mysql`?

This is output of `docker ps | grep mysql`

How much memory do you have on your computer? `free -h`

Can you try to run the mysql container on its own?

```auto
tutor dev stop
tutor local stop
tutor dev run mysql

```

I stopped all containers and ran the command `tutor dev run mysql`, and got this result.

Your mysql container seems to be working just fine. Let’s delete all containers and try to restart the platform:

```auto
tutor dev dc down
tutor local dc down
tutor dev launch

```

Hi everyone @regis ,

I am having the same issue, so here is my background using windows:

1. Your mysql container is crashing/restarting in an infinite loop. What’s the output of docker ps | grep mysql?  

2. How much memory do you have on your computer? free -h  
 ![image](https://us1.discourse-cdn.com/flex020/uploads/openedx/original/2X/4/4d3989f3a37c2049189a9e4e36cd4d34c2909e83.png)

3. Can you try to run the mysql container on its own?  
tutor dev stop  
tutor local stop  
tutor dev run mysql  

4. I’ve tried this but no use:

```auto
tutor dev dc down
tutor local dc down
tutor dev launch

```

Can you help me with this?
