Is that NiFi secured? If so, did you attempt to access it via HTTP (vs HTTPS), or vice versa (HTTPS to an unsecured NiFi)?

Alternatively, were you running a flow at the time? If so, what were the processors involved? The version of Jetty was upgraded in NiFi 1.0.0, but I'm not sure what (if anything) is different between 1.0.0 and 1.1.0 with respect to Jetty.
