W4SP Lab has something broken and needs fixing. Below is the suggested startup that throws the error followed at the bottom by the docker status that shows how it failed:

For this issue, I have spent about 2 hrs at current time to figure out why this error continues to persist. After doing some research it is believed that this might be a issue on older versions of docker. As a result, I have begun updating docker packages in order to mitigate this issue. If this does not work I will be forced to add new python code to fix the current issue.
