Assuming you have all other login info correct, I can only guess that you are still using the incorrect mysql host (highlighted above). This host address is not the same as your website url. It should be like mysql##.000webhost.com as per your cPanel/MySQL info, and not the account info on right side of cPanel showing your website address etc.
If you are usingthe correct MySQL host address, then I can only guess that something is amiss with your IP. Are you using a proxy server to hide your IP?
