Director: FreeBSD 12.2, bacula-server-9.6.6 from pkgs
Client: OpenBSD 6.8, bacula-client-9.6.5 from pkgs

After upgrading a bacula client's OS from OpenBSD 6.7 to 6.8, nightly
backups run successfully but throw this warning:

ERR=20:"unable to get local issuer certificate"

This setup uses self-signed certificates and worked without errors or
warnings before this OS upgrade.

There has been no bacula configuration change on either the client or
director . A diff of the client bacula-fd.conf file (excerpted below)
before and after the upgrade shows no change.

I tried revoking the old client cert and generating a new one, but this
had no effect on the warning message.

I also tried command-line "openssl s_client -connect" commands both
ways. Both connections worked on the respective ports 9101 and 9102.

Besides the bacula client configuration -- which hasn't changed, aside
from pointing to new certs with the same filenames -- is there something
else that needs tweaking on the client?

Many thanks.
