Hi @MantuDeka ,

A few questions:

1) Was the Hue UI working before? Any changes to the Hue service before users noticed the issue? 

2) Is this issue happening to single user or multiple users?

3) Have you tried to use different machine/browser to log in and see if this issue resides on server side or client side.

I suggest you trying to clear the browser cookie/cache and see if that helps.

Thanks and hope this helps,

Li

3) Have you tried to use different machine/browser to log in and see if this issue resides on server side or client side.

Ans- Different machine means you want to install HUE service in another machine ? Its already running in masternode.
