Manually report like you do today until the error is resolved. Additionally, you could:
- Ensure that all Usage Meter instances have network connectivity and are able to send reports to UMS.
- If a private key on the Usage Meter instance was changed, reports were received but could not be decrypted. The key should be changed back to the original key.
- Check that you have setup sites in UMS as defined in the UMS.
