unable to connect to my wordpress admin panel on ubuntu 16.04
I followed the Digital Ocean tutorial on how to install WordPress on Ubuntu:
I managed to set up a WordPress successfully, but then I accidentally closed the tab where I was working and from now on I cannot access to the WP admin panel.
I can successfully visualise my new blog by typing my server’s IP, but I cannot actually log in to my WordPress admin panel at http://DROPLETIPADDRESS/wp-admin (DROPLETIPADDRESS = IP address of course), I get an error:
“Unable to connect.
Firefox can’t establish a connection to the server at xxx.xx.xx.xx.
- The site could be temporarily unavailable or too busy. Try again in a few moments.
- If you are unable to load any pages, check your computer’s network connection.
- If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.”
what can I do now?
