Error with a install of xibo docker

we are testing Xibo through docker on my main machine and I am getting this error.

I have no special ports that need to be configures, it should be a standard install but the error shows when I run the “docker-compose up -d” command

I have tried it on a different computer and the same issue

Get https://registry-1.docker.io/v2/: x509: certificate signed by unknown authority

Are you using a filtering proxy server that spoofs SSL certificates by any chance?

If so, you’ll need to have that CA certificate trusted by your computer before it will be trusted.

I’m not sure if it’s a Windows or Linux PC, so I can’t advise on how to go about that.
