Hi All,

I am getting following error after upgrading my Indexer from 7.2 to 8.0.

Don't think it's a network issue as it was working before upgrade. Not sure about compatiblity as current peer is on 8..0.2 and Cluster Master is on 7.2

Can anyone please suggest what could be the issue.

Always upgrade the Cluster master first, then the peers. See documentation https://docs.splunk.com/Documentation/Splunk/8.0.2/Indexer/Upgradeacluster
