Hey friend,

There are a few layers this could happening at. The first thing you want to do is ping the droplet IP to see if it responds. If it does not (under average conditions, avoiding mention of all possible exceptions), then your droplet most likely has no network connectivity. This means that something changed on the droplet that caused it’s networking to fail. There is no one correct path to resolving that, it has to be found where it occurred. It could be anything from the flip of a default firewall chain policy to a broken configuration. A few of us put this together not too long ago:

If it doesn’t get you anywhere, feel free to open a ticket with our support team. There is likely more information here than simply removing Nginx and Apache if that is the case, and it may be important for you to give more details about what steps you took to install Nginx and then what steps you took to replace it with Apache. If you used any installer scripts, pasted commands from a tutorial, etc.
