Cluster become red

Hi colleagues, after migrating my Elasticsearch cluster from Docker 6.2.2 version to VMs with 6.8.5 version, my cluster periodically get RED status. In logs I see that some node left the cluster. On the node that left cluster I see only messages like "node [NlxDLTjjQMi4tWf_2PPAVQ] is not available"
But I don't see any network issues.
I have 5 nodes
