Cluster syncronisation error

[DG]

Hello Community,

We have a fresh set up Jira Service Management as a Data Center version in the cluster with a postgres DB.

We get a some cluster error and could not found the cause.

What we have done:

 - Clustering - Node status / Application status  ✓

 - Check - cluster.properties ✓

 - Check - open ports ✓

Does anyone have an ideas what we can check?

Hello DG,
Did you solve your replicate cache or not?
