Event id 30807 recorded

I have 6 Remote Desktop Server (Windows server 2019) hosted on AWS. Periodically i found in the SMBClient log of event viewer 30807 event. After some time (10-30 minutes) 30806/30808 are recorded and the problem is resolved.

I have some shares on one server and these during the lasting of the problem are unreachable..

Someone have resolved this?

Thanks in advance
