PENDING MP has rejected a message from GUID:XX error 5447

[awachens]

Hi all,
Can someone tell me how to troubleshoot this?

I have a lot messages like this:

MP has rejected a message from GUID:XX because the signature could not be validated. If this is a valid client, it will attempt to re-register automatically so its signature can be correctly validated.

I know what is the hostname of the devices but i dont know what is the next step.

Regards,

Log files and screenshots will help. Have you made any changes on the MP?
