Hello,
I have i running cluster ad I have to add a new host.
Current cluster has AMD type cpu, new host has intel CPU su I added a new cluster in same datacenter (datacenter default compatibility 4.2).

New Host is running node 4.3.4, engine is 4.3.4.3-1.el7

The new host is attached to ths new cluster, but engine can't connect.
Engine logs tell me:
