Hi,

As you said that all hardware side you had verified that everything is working fine. What is the hardware model and software version?

We noticed the same issue was reported due to a bug and multiple models were affected.

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvi89146/?rfs=iqvred

Workaround:
Re-seating the stack-power cables has been observed to clear this issue in some cases.
