SM deregistered - Elevate auth failed due to packet loss

I have problems with AP ePMP3000.
Some MS dislodge reporting this message:
SM deregistered - Elevate auth failed due to packet loss
Licenses are in the cloud and work on my other ePMP2000 APs
How can I solve it?

Hello,

Usually, this message is shown when high interference level is introduced what causes mgmt packets corruption.

Please try to move AP to another cleaner channel.

Thank you.
