 | `IGN-NETWORK-2` | Port is already in use. | Most likely, Apache Ignite tried to access the port occupied by a different process. Change the port or free it, and then restart the node. |

 | `IGN-NETWORK-5` | Recipient node has left the physical topology. | Check the error message. The node is unavailable and need to be brought back into the cluster. |
 | `IGN-NETWORK-6` | Could not resolve address. Most likely, the IP address specified in the operation is not available locally. | Change the node configuration to make the address available or use a different IP address. |
