Network Error: Software caused connection abort. Can not connect to server
I am using ubuntu 16.04 for my magento. I can not able to login into server as it cause connection issue when i try to login using Putty. I can not able to locate /var/www/html/ directory structure where I have put my files and folders.
Is there any command I need to run in order to get that structure back? Help me to solve connection issue problem so I can able to login.
