I’m not sure if this has anything to do with your DDoS issues and intermittent up times … but I have been getting a forbidden error on my site paganmingle.000webhostapp.com I am also not able to access via FTP however the dashboard file manager is working but my home directory is empty?!?
“Forbidden
You don’t have permission to access / on this server.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.”
