Hi Nitin,

Can you please try opening Kibana in a new Incognito or private browser tab and see if you still have the problem?  
If that works, the problem might be caused by something cached in the browser and if you cleared your browser cache that may resolve it.

Which browser is it? Have you tried any other browsers?

Thanks,  
Lee

Thanks for the reply @LeeDr.

I tried opening it in incognito mode but it's giving the same exception. Also, I am opening a load balancer URL which is pointing to two kibana instances, do you think this might be the issue?

I am opening it in Google Chrome Version 56.0.2924.87.

Thanks  
Nitin

Yes, I think it's very likely that your load balancer has something to do with it. Can you try accessing those Kibana instances directly?  
What kind of load balancer is it?  
Can you see anything in the Kibana logs?
