My problem is I created a mysql droplet and added a domain to it. No problem there. I can reach it from my home computer url for the mysql droplet is like mysql.test123.com.
Next thing I did, was creating an asp.net Web API and deployed it with in memory database. Neither a problem.
Now I tried to make the api use my mysql database via the url mysql.test123.com. And there is the problem it can’t reach the host.
Next thing is I tried to ping the ip. worked like a charm. Tried to ping mysql.test123.com - unknown host. I can’t even ping my own domain

So any pointers to solutions?
