This message appears for all commands even when I just simply type docker.

Here is a error log while using Docker SDK for python

```auto

I also changed the topic title. Please always chose a title that shortly describes the issue instead of only saying that it is an issue, which is obvios. Thank you.

Regarding the error message it seems pretty clear about that you used the http potocol when it would require tcp protocol. As you cans ee in the error message, tcp was added before the url, so you don’t even need to define the protocol. Just use the IP address and the port.
