impossible to delete the address
Thank you, this worked for me.
Plesk on AWS EC2 came with 2 IP address one of them went awol after assigning Elastic IP. Then I added more Elastic IP addresses.
That awol IP address was set as the primary IP address on Plesk.
Rajeev Bagra Try Plesk-> Tools & Settings -> Tools & Resources -> SSH Terminal
After a restart, the settings unfortunately reset themselves.
I guess they are wrong somewhere in the network configuration from Server?
