Various problems with bundle replication; unauthorized and generic error

[manderson7]

Running a 2 site indexer cluster configuration, with 2 search head clusters.
Site 1 shows a search head with the following error:

Search peer site1sh08u has the following message: Bundle Replication: Problem replicating config (bundle) to search peer ' 172.30.63.42:8089 ', error while transmitting bundle data.

Site 2 is showing the following error:

Search peer site2sh01u has the following message: Bundle Replication: Problem replicating config (bundle) to search peer ' 172.31.133.16:8089 ', got http response code 401 HTTP/1.1 401 Unauthorized.
Search peer site2sh01u has the following message: Bundle Replication: Problem replicating config (bundle) to search peer ' 172.31.133.17:8089 ', got http response code 401 HTTP/1.1 401 Unauthorized.
Search peer site2sh01u has the following message: Bundle Replication: Problem replicating config (bundle) to search peer ' 172.31.133.18:8089 ', got http response code 401 HTTP/1.1 401 Unauthorized.

What authentication is the message from site 2 referring to? Where can I find more information about these messages?

Never mind, looks like a restart of all the search heads did the trick.
