UnrecognizedBrokerVersion: Current client is 1.3.5, Latest client is 1.4.2

[wbarnha]

This started happening last week. The client has not changed versions. The server has not changed versions. All of the builds are occurring in identical environments, for all intents and purposes. We're running a high-volume of builds every day and it's happening once every four or five hours.

The server is on 2.12 .

Any ideas?
