I'm trying to run the Duplicati backup program, which relies on mono to connect to remote storage such as Amazon S3, or BackBlaze B2 (which I use). I'm getting CERTIFICATE_VERIFY_FAILED error.

The release notes from Mono suggest that a manual sync shouldn't be needed on RedHat derivatives, but adds that cert-sync is available "which synchronizes the Mono SSL certificate store against your OS certificate store"

sudo cert-sync /etc/pki/tls/certs/ca-bundle.crt

is returning:

What needs fixed to connect securely to internet services using Mono?
