CISCO UCS Login error java.io.IOException: Invalid Http response Login Error: java.io.IOException: Server returned HTTP response code: 400 for URL: http://x.x.x.x:443/nuova

If you receive the following error:

java.io.IOException: Invalid Http response Login Error: java.io.IOException: Server returned HTTP response code: 400 for URL: http://x.x.x.x:443/nuova

It’s a java version problem!

The easiest way to be able to login to the fabric interconnect is to enable http login and disable http to https redirect (also if it’s not the safest way!):

Login via ssh or console and enter the following commands:

scope system

scope services

enable http

disable http-redirect

You should then receive the following warning:
