Need help with Reviving a Indexer on AWS. The error say "unreachable" Thanks a million

[SamHTexas]

Our SHs & Indexers are clustered. Not sure if this has to do with AWS going down yesterday. But I noticed the error early today & it has red exclamation on it at end of the day. Restarting the cluster master did not help. Thanks & Happy holidays.

Have you tried restarting the indexer?
