Bad request error in localhost after adding new app

I am new to frappe and erpnext. I installed bench in a virtual machine (with OS ubuntu 14.04 32 bit), using easy install, and followed the tutorial to create a library_management app. After adding app and site, when I do bench start and hit localhost:8000 in browser, I get HTTP 400 error in the terminal and browser says Secure connection failed with error code: SSL_ERROR_RX_RECORD_TOO_LONG.

Please someone help me to sort this. Is this because of something in my browser, or in app?

If it’s just for locsl testing you could edit the nginx config to remove the ssl entirely and just keep port 80. But yes an odd error
