Invalid certificate LE

Hi, I’m trying to self host Jitsy with docker.
I’ve successfully generate a certificate for my domain as stated in the container logs:

  • Congratulations! Your certificate and chain have been saved at:
    /etc/letsencrypt/live/my.domain.com/fullchain.pem
    Your key file has been saved at:
    /etc/letsencrypt/live/my.domain.com/privkey.pem
    Your cert will expire on 2021-02-25. To obtain a new or tweaked
    version of this certificate in the future, simply run certbot-auto
    again. To non-interactively renew all of your certificates, run
    “certbot-auto renew”
  • Your account credentials have been saved in your Certbot
    configuration directory at /etc/letsencrypt. You should make a
    secure backup of this folder now. This configuration directory will
    also contain certificates and private keys obtained by Certbot so
    making regular backups of this folder is ideal.

But when I visit my.domain.com chrome warns me that the certificate in invalid. How can I solve that? Many thanks.
