Hi :wave: @feng_deng,

Welcome to The MongoDB Community Forums! :sparkles:

I presume that you are working with MongoDB Ops Manager. The issue seems to be with your configuration/environment.

I would recommend you open a support case at MongoDB Support Portal as they have the required expertise and could help you with root cause analysis and provide the best solutions as per your use-case.
