Hi Igniters,
We have three server nodes, there is firewall between clients and servers.
Opened 47500 and 47100 series ports, but still below errors are printing at
client side frequently. But client application able to get data from cluster,
could please help us how to avoid these errors at client side.
We are using Ignite 2.7.0 version.
