When checking the dns with dns validators there are some issues reported:
Primary Name Server Not Listed At Parent
Status Warning SOA Refresh Value is outside of the recommended range
ns1.domain.com reported Refresh 86400 : Refresh is recommended to be between 1200 and 43200.
Status Warning SOA Expire Value out of recommended range
ns1.domain.com reported Expire 3628800 : Expire is recommended to be between 1209600 and 2419200.
I'm not sure where that placeholder comes from? I can't find it in the dns editor in the panel... The soa refresh and expire values should be set somewhere between the recommended values to make sure all external services play nice with it. Or is there a reason why they are outside the recommended values?
