Didn't someone suggest earlier that the nodes/messages url is for fetching message calalogues for translations, or something like that. Is nginx blocking that url?

But it is not blocking before addition of modules

</div>

In that case it is the fact that the modules are installed is causing that data to be fetched.

As @Steve-Mcl said : Some plugins and nodes load a message catalog (for internationalisation) from the endpoint `messages`

Is it one specific module that you've installed that triggers this behaviour? This could simply be a bug with that one particular module.

Do you mean that with no extra nodes installed that it works ok, but as soon as you install just node-red-dashboard that you see the problem?

Check in the browser console on the working system that you do not see any errors. Do not rely on it just appearing to work.

@Vikas-Konaparthi it is quite hard to help if you post an error message with no context on where you see it. Is that in the browser javascript console? Is there _any_ more information such as a stack trace or anything in the Node-RED log itself?

Yes Colin as soon as I install I am getting error this is any issue with the nginx nodered related thing.

Can you set the log level to trace in settings.js, restart node red and post the startup log please. That is the log with the Welcome to node red message.  
If you connect the browser locally, so not through nginx, is it ok?
