Resolution
Verify the interface mac address(HWADDR) with the interface /etc/sysconfig/network-scripts/ifcfg-eth0 file
If it is different from the one which is showing under interface using the command ip addr show like this:
Then edit the network interface ifcfg-eth0 file by using this vi editor:
vi /etc/sysconfig/network-scripts/ifcfg-eth0
Press i to put in insert mode, change the HWADDR value same as the current value and save by pressing Esc :wq
Restart network service using this command:
systemctl restart network
And it will assign the IP configuration as defined in the ifcfg-eth0 file like this:
Once the IP is assigned, restart the Phoenix service using this command:
systemctl restart Phoenix
