Make sure you have updated in the nodebb configuration with the property
"isCluster": true
When you use auto sclaing(HPA) of NodeBB, this is must. Otherwise you will end with lot of inconsistency in the API responses.
Note: This property will help if you use on Redis as your DB(not with the conbination of Mongo+Redis)
Thanks for the details mentioned in this post
