Hi I have wrote a java program to perform CRUD operation and now when I tried running my code First I got this on the console window :- "**Started Application in 8.539 seconds (JVM running for 9.069)**" and later just after this line I got a error message:- "**[Glob] failed to get node info for {#transport#-1}{127.0.0.1}{127.0.0.1:9201}, disconnecting...**, followed by many other error like **failed to load elasticsearch nodes**". I have attached a snapshot as well for more clearification. Also I have tried fixing the error. More info:- I am using elasticsearch 2.4.0, using spring tool suite as IDE. Kindly, help me. ![Connection](https://us1.discourse-cdn.com/elastic/original/3X/b/5/b5d416f60a3e5d2bb7b179e09fb21297e0f2e050.PNG) Best regards, Vivek Ranjan ---

Please don't post images of text as they are hardly readable and not searchable. Instead paste the text and format it with `` icon. Check the preview window. I don't see your code but I believe you used the wrong port here. ---

Ok I will paste the code here. Thanks for reverting back. The issue is I have 2 laptop and on one laptop same piece of code is working fine but when I import the code in this PC it's not working here. Thanks. ---

Is elasticsearch running on your local machine? ---

Yes it is working now. The issue was, I had 2 different versions of elasticsearch in my PC and then I was trying to run my code. Now I have deleted the 6.3.1 version of it and it is working fine. Thanks for your help 😄 ---

@dadoonet I have one more doubt, I wanna run this application using elasticsearch 6.X.X version(latest) so can you please guide me the way to achieve it. I have tried it but was getting the shared error alongwith the elasticsearch version is not compatible. Thanks. ---

I don't really know how to fix that on Spring boot side. May be you have to overwrite the default transport client which is defined by Spring? ---
