The first thing you need to do is make sure that your droplet is online at all. Testing outbound traffic is sufficient for this case. Try pinging servers that you know should respond, like:
Or even:
If these fail, your droplet’s network may be down or your firewall may be blocking the outbound traffic. Try disabling the firewall for good measure. One of these commands should do it:
If this has no impact, and all outbound traffic is still failing, reference this post:

If you did actually confirm that outbound traffic is working, just not to the end-point that you are trying to reach, then you should try running an MTR to see where it fails. You can find a tutorial to help you with that here:

Where the MTR drops will determine who can remedy this. If it drops right before reaching the end point, at the datacenter for the other server, then the other server is likely blocking your traffic. If it drops inside of our network, perhaps you should open a ticket and give us the MTR results:
