DNS resolution failed

[Henrik Bossart]

I am using the beta version of the Google Ads Api (v2), and suddenly started receiving this error:

                }
              ]
            }
          ]
        }
      ]
    }
  ]
}

I haven't seen this error before, and was wondering what to do about it? I can't find anything about it in the API docs either..

All help is appreciated.
