I’ve added a floating IP but the IP address just won’t work. Pinging the newly created floating IP will get request timeout for icmp_seq 0. SSH also doesn’t work.
I have tried changing my domain name A record to the floating IP but then the website just won’t load anymore and I am forced to change it back to the original IP.

In my case - it was a missing firewall rule that prevented my droplet from responding. The thing is that I’ve assigned the floating IP while my droplet was off. However, I’ve unassigned, and when assigning again, I got the nice popup with hint that droplets created before some time in 2015 must manually be added a firewall rule. After I did that all was good.
Go to Networking >> Floating IPs >> Select your expected floating IP >> More >> Reassign and a Pop-up window will come up saying you to run some commands for you old Droplet.
If you run tcpdump on the host the floating IP is intended to point to you may see that incoming traffic is from the internal (10.x.x.x) network.
Adjust your services accordingly to ensure incoming data can flow from the DO service that hosts your floating IP to your primary Droplet.
