Hi Sandy,

I've the same issue;

I'm checking with network, did you solve?

I'm in a clustered installation (OBIEE 12c - 12.2.1.2.0), two linux machines behind a load balancer.

I've checked

hosts file which map correctly to my two servers

resolv.conf

point to internal DNS

nameserver 10.X.X.70

nameserver 10.X.X.71

search <mydomain>.it

both looks good to me.

Any help?

Regards,

marco

These errors look like network related, so I would check with your network team. Is there a load balancer involved?
