Hi team, we are seeing the following error from FE, that it fails to connect CN via RPC

Fail to publish version for tablets:[], error msg: link rpc channel failed, host: starrocks-cn-1.starrocks-cn-search.starrocks.svc.cluster.local

Does anyone knows what might be the reason?

It's possible the CN is overloaded. Can you try ping the CN node from the FE. Also check the

<http://cn.INFO|cn.INFO>

and

cn.WARNING
