Currently, some of our nodes are overloaded. The nhc installed used to

It seems that it is not able to read the state of the node. I ran scontrol
show node mcn26
NodeName=mcn26 Arch=x86_64 CoresPerSocket=16
NodeAddr=mcn26 NodeHostName=mcn26 Version=20.11.8
Any idea what happened and why nhc is not reading the state of the node
anymore?
What's the complete output of "scontrol show node mcn26", especially the
State=... information?
Which version of NHC are you running?
