@yadav1990 - please stop necro-posting on very old threads, and instead start a new thread with your question, or continue your existing thread. This is a community forum and not an official support avenue; if you need priority support for issues, I’d be happy to get you in touch with someone to discuss your support needs.
Please try the suggestion above first. Depending on the results, you can try increasing the timeout on the join method (or through other client settings you can find in the Javadocs). (Reference thread - please continue the conversation and troubleshooting here, however.)
