hi,

I encountered [this issue](https://github.com/akka/akka/issues/29983) on our production cluster.

I wonder if anyone else has experienced the same problem.

I doubt it is a configuration issue on our side because the workaround config we used did work.

Do you have a downing-provider configured?  
In my case (the related issue) the problem was solved by adding the following to the application.conf:

```auto
akka.cluster.downing-provider-class = "akka.cluster.sbr.SplitBrainResolverProvider"

```

You can use SBR since it’s free.
