update: this depends on wget ... which seems unable to verify the certificates.

Looking into this, i could not find ANY root certificate store with the exception of /etc/ssl/certs/ca-the_usertrust_network.pem

it's also needed to add the issuer root CA (Let's Encrypt root CA) certificates to the certificate store.
