Erp next installation

whever i do ‘ssh -i “frappe.pem” ubuntu@ec2-52-40-49-212.us-west-2.compute.amazonaws.com
in my .ssh folder in windows it show me :- "ssh: connect to host ec2-52-40-49-212.us-west-2.compute.amazonaws.com port 22: Connection timed out " . I am using windows 8.1 and using cygwin as command line tool for windows . Also it shows the same error while i am connecting via ssh putty to login to linux machine …what to do ?. plz help

i cant install this on my linux ubuntu as i need this so that i can connect it to magento 2,1 community edition and i have facing some issues regarding magento in linux so decided to install it on windows but now i need erp next on windows to work with both in parallel on same os . So suggest any thing about this issue keeping windows 8.1 in mind .

It not seems to be an erpnext problem …sound like a ssh connection prob …imho
