title: Traefik Default certificate is not trusted
body: <p>The configuration below worked fine until I moved the location of the docker-compose.yml file.
  Now I got the invalid certificate message in the browser "This CA Root certificate is not trusted because it is not in the Trusted Root Certification Authorities store." for the self-signed certificate.
  Not sure what is causing the problem.</p>
