Hi Karthik and Others,

I am not able to bootstrap with Eureka with the latest code.

I keep getting an error Connection to http://localhost refused. I did take a look at DefaultEurekaClientConfig.java for a similar issue that was reported earlier.

That portion of code has changed and I am not sure if the new code is introducing anything.

I am trying to run this in Ubuntu - A single box where server ,client and application services are running.

May be I am missing something basic. Would appreciate if someone is able to point out what am I doing wrong.

Thanks in Advance,

Saswat
