Whenever you get an error code like that, you have to call Amazon support to fix the issue.
In the past, other forum members have reported similar error codes with different numbers. The issues ranged from moving to a country that Amazon did not officially support on the Alexa platform, to buying a used Echo device and the original owner reported lost/stolen. In any case, you have to talk to Amazon support. Some issues can be resolved very quickly (within a few minutes) after talking to Amazon support.
