If you are using private DNS and use a domain name like "readynas.fool" then an error is thrown.
The number of root domains is growing rapidly, I don't know what sort of checking is happening, but it looks like the validation is making bad assumptions.
Re: 6.2.1-RC3 throws error on valid FQDN in Backups
Is this for a new job, or are you modifying an existing job? I just tried it, and it works for me with a new job, but does not work on an existing job. Either way, it needs to get fixed, but there does appear to be a workaround for now.
