When your app sends a an ad request, our server occasionally returns a sleep. The following is a list of the most common reasons for a sleep:
|The ad request was successfully sent and received, and an ad was sent back.
|Server errors are channeled to sleep codes in this range. Such errors should not occur frequently.
|Unaccounted server error
|The ad request was made from a device that doesn't match the Test device IDFA/ GAID in the Dashboard.
|The app ID is configured to only serve when the device is connected to WiFi, and the request was made with a cellular connection.
|Publisher not found
|Publisher app ID is not found in Liftoff database.
|No active campaigns
|There is no active campaign in the geo location from which the ad request was sent (based on the device IP address).
|Impression auctioned not sold
|The Liftoff ad server did not receive a valid bid from any of our bidders. The sleep time is incremented in 60-second intervals from 605 up to 1805.
|This is caused by a load balancer issue, which should be very rare.
|Filters eliminated all options
|Dashboard configuration options, such as minimum OS version, have filtered out all campaigns for this ad request.
|Exchanged removed all campaigns
|Liftoff's ad server did not receive a valid bid from any Vungle Exchange bidder.
|Filters cropped publisher whitelist
|There is a conflict between the settings defined in the Dashboard. For example, whitelist or blacklist settings under the account, application, or placement level are in conflict with those in another level.
|This happens when your app is set to inactive in the Publisher Dashboard. Change the app to Active or Test mode and try again.
|Publisher Daily View Limit
|The daily view limit (DVL) has been reached. This is set to 20 by default; to change this value, contact our technical support team.
|Publisher app ID is set to inactive mode.
|Below minimum OS
|The ad request was made from device that does not meet the minimum OS version. This sleep can also indicate that the ad request was made from a platform that is different than what is specified on the Liftoff Monetize Dashboard.
