Please read carefully.
2 years ago I setup WHM on a Centos server on Digital Ocean. At the time my Digitial Ocean server had a floating IP attached to it.
This floating IP was not used during the cPanel setup, and is no way related to any of the domains on my server, or the actual cPanel itself.
Because of this cPanel allowed me to delete the floating IP within the WHM control panel yesterday, because it was not attached to anything.
For some reason now 100% of my websites are no longer working, some sort of networking error. So it seems that the floating IP was somehow related to entire system running, but I have no way of identifying where this IP is being used or how to change it over to the other IP which should be the only one associated with anything.
i have 6 years of experience as Network and system administrator . i have experience with centos web panel Kindly contact me so i can look into your issue
