Error when saving DNS Resolver configuration

gibbsy81 · February 2, 2020

Hi All,

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
[1580637057] unbound-checkconf[94278:0] fatal error: server-cert-file: "/var/unbound/test/unbound_server.pem" does not exist

I have tried so far.

Restarting Pfsense
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.

How about downgrading to older, but more stable build with default settings? No personal experience...

Did you read the error? You are missing a certificate file, either for DoT or DoH (because can't think of any other reason why Unbound would use PKI).

I assume you were running the test build before as well? As normally unbound configuration is contained in /var/unbound/ not /var/unbound/test/.

Last I checked it was well documented that unbound has open issues on the test builds of 2.4.5, its why I had no intention of upgrading until the stable version.
