Cluster Peer Configuration Error


I have 2 indexers and 1 CM and I was able to add one indexer to the CM cluster but not the other one. The first indexer also is currently ingesting all the logs and has all the indexes and the new indexers spits out an error as soon as I try to add to the cluster.
please see below for the error. Not sure whats going on.

Did you check that tcp 8089 port is open between CM and indexers?
