Problem with my email configuration and Docker daemon error.

[Simon-Piquemal]

Hello,
I currently have two issues with an application installed on my server.

Email Provider Issue: I have a notification about an email configuration problem. I used my professional domain name, which is a custom domain connected to Gmail's base providers, and backed by a Google Workspace subscription for managing emails. I attempted to use the email on the app like a regular Gmail address, but I am facing connection issues. The error message I receive is: "Email is not configured properly."

Docker Application Issue: For storing images, I managed to install the application image on Google Cloud. When I open the app, there are no applications inside it. When I try to execute commands with the username and password, I receive an error stating that the Docker daemon is not running. Specifically, the error message is:
docker login docker.mycustomdomaine.fr
Username: my user
Password:
error during connect: this error may indicate that the docker daemon is not running: Post "http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/auth": open //./pipe/docker_engine: The system cannot find the file specified.

Could anyone provide solutions for these issues? If needed, I can grant support access to my server for a closer inspection.

Thanks in advance.

I've solved the docker daemon problem, I just couldn't start my docker on my pc. But for the rest of my problems I still don't have an answer.
