Error Code 0 : ERROR_CODE_INTERNAL_ERROR
This indicates that something happened internally; for instance, an invalid response was received from the ad server.
Newly created Ad Units can take upto 2 hours to become active (SpinUp Time). Any Ad requests from newly created Ad Units would also receive Error Code 0 in response to Ad requests until they are ready to serve live ads.
