The log is not showing my email

[itr6]

vpn.Domain2.com {
  tls [email protected]
  header / Strict-Transport-Security "max-age=31536000;"
  gzip
  proxy / https://IPADDRESS:PORT {
    insecure_skip_verify
    websocket
    transparent
  }
}

This is my caddyfile but when I run my docker command, I dont see my email address. This is the log:

Is this normal? Is my caddyfile wrong? Can my email differ from the domain I want to get the cert for? Any help would be greatly appreciated.

This is my docker command:

docker run --name caddy -e "ACME_AGREE=true" -e "CADDYPATH=/etc/caddycerts" -v /home/user/docker/caddy/.certs:/etc/caddycerts -v /home/user/docker/caddy/Caddyfile:/etc/Caddyfile -v /home/user/docker/caddy/srv:/srv --net=host abiosoft/caddy
