Mediation upgrade errors

In the process of upgrading your account, you may encounter one of the following errors. Expand the sections below to learn more about each error and how to fix it.

 

The upgrade did not complete because AdMob does not support more than 500 mediation groups. 

Cause:

Your existing mediation setup generates too many new mediation groups during upgrade. This is most likely due to the number of country-specific settings in combination with the number of ad networks in your mediation chain. During the upgrade, new mediation groups will be created to account for all of these individual country or regional settings and ad networks.
 

To fix this error:

Reduce the number of country-specific settings and/or the number of ad networks used in your existing mediation setup, and then try upgrading your account again.

The upgrade did not complete because AdMob does not support more than 30 ad networks in a mediation group. 

Cause:

There may be too many ad networks in your mediation chain.
 

To fix this error:

Reduce the number of ad networks in your mediation chain, and then try upgrading your account again.

The upgrade did not complete because the eCPM for the AdMob Network is set to zero, which disables the network.

Cause:

Setting the AdMob Network's eCPM value to 0 disables the AdMob Network in your mediation setup.
 

To fix this error:

Adjust the eCPM value for the AdMob Network to a number greater than 0, and then try upgrading your account again.

Your existing mediation setup contains targeted locations that are no longer supported.

Cause:
Some countries cannot be targeted in AdMob mediation. Your existing mediation setup is targeting one or more of these countries.
 

To fix this error:

Review the list of unsupported countries. Remove any country that appears on the unsupported countries list from your mediation setup, and then try upgrading your account again.

In addition to the list of unsupported countries, targeting Myanmar (Burma) may also trigger this error message.

Your existing mediation setup contains deprecated networks that are no longer supported.

Cause:
Occasionally, some ad networks may be deprecated and no longer supported in AdMob mediation. Your existing mediation setup is targeting one or more of these ad networks.
 

To fix this error:

Review the list of deprecated ad networks. Remove any ad networks that appear on the deprecated ad networks list from your mediation setup, and then try upgrading your account again.
