Problem description
Backup jobs remain in a Queued state because the SQL plugin cannot enqueue jobs to the local Falcon service due to a TLS trust failure. The error in logs:
tls: failed to verify certificate: x509: certificate signed by unknown authority ("Druva, INC.").
Cause
The Druva Falcon service uses a self-signed certificate that was not present in the Windows Trusted Root Certification Authorities store. This causes TLS verification to fail.
Traceback
