I am currently running Pfsense with the DNS Resolver feature.
I have noticed that Unbound has crashed and will not restart when trying to apply any configuration changes i receive the following error.
The following input errors were detected:
The generated config file cannot be parsed by unbound. Please correct the following errors:
/var/unbound/test/unbound_server.pem: No such file or directory
 unbound-checkconf[94278:0] fatal error: server-cert-file: “/var/unbound/test/unbound_server.pem” does not exist
I have tried so far.
Copying /var/unbound/unbound_server.pem to /var/unbound/test/
Updating Pfsense to the build 2.4.5-RC build.
Updating to the 2.4.5-RC build did fix the issue for a little while however not for long.
Please let me know if you need any further info.
Thanks in advance.
