    Hi Narasimha,

    1. What has changed between the working and non-working setup? Did you change the broker, port number?
    2. Are you connecting to an external/open broker via getHostByName? If yes, then can you please check the internet connection or try after sometime?

    Regards,

    Hello Raghavendra,
    Thanks for the reply.The issue got resolved i think during that time there was some internet issue and also the m2m.demo.ibm was not able to connect.may be the ibm server was under maintanance,or not responding at that moment.
    1.No code change done.
    2.yes iam connecting to external connection to publish and subscribe data.
    Please close this issue its resolved,there are other couple of queries that i will create new threads.

    Regards
    Narasimhajb
