The first seed node won't join the cluster via other seed node after restarting


I encountered this issue 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.

found a related issue:

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:

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

You can use SBR since it’s free.

we had it. unfortunately, it didn’t solve the issue. I also tried disabling it, which didn’t help.

I posted more logs in the GitHub issue.
