Error loading image from docker engine: error during connect: (Windows 10 Pro)

Hi.

I use it in windows 10.

$ img2lambda -i lambda-tesseract-ocr_tesseract:latest -r ap-northeast-1 -o 
./output
2019/10/16 10:24:00 Parsing the docker image docker-daemon:lambda-tesseract-ocr_tesseract:latest
2019/10/16 10:24:00 Error loading image from docker engine: error during connect: Get https://%2F%2F.%2Fpipe%2Fdocker_engine/v1.22/images/get?names=lambda-tesseract-ocr_tesseract%3Alatest: dial tcp: lookup //./pipe/docker_engine: no such host

Docker TLS check is enabled

And the environment variable sets the value.

$ echo %DOCKER_HOST% 
tcp://localhost:2375

How can I verify the validity of the tcp://localhost:2375 ?

thanks.

$ img2lambda -v

$ set DOCKER_HOST=tcp://localhost:2375 && img2lambda -i lambda-tesseract-ocr_tesseract:latest -r ap-northeast-1 -o ./output

Somehow it started to move.

VS Code did not read the updated DOCKER_HOST.
After restarting VS Code, there was no problem.
