I cannot define a reverse DNS Server via Web-UI. everytime I want to save the config i get the following error without saving:

I have to remove the server on "inverse dns section" and uncheck the "private reserve" option. BTW: Is "inverse dns" the same like "reverse DNS"?

I defined the setting via yaml config file, but doesn't work either:

  private_networks: []
  use_private_ptr_resolvers: true
  local_ptr_upstreams:
    - 192.168.1.1

The private_networksdoesn't work either.
