Node-RED: v4.0.9  
Node.js: v22.14.0  
NPM: v10.2.2

today I installed the same Nodejs and Node-RED in two different places for project testing. One in my own laptop, another in a lab server (where constraints exists for public network access, a http proxy must be used to access), nodered environment in my laptop works well; nodered environment in lab server has issues, the entry page load failed, an empty page is populated and there's some errors when checking browser console with F12.

Any kind advise on how to get rid of those errors and let nodered work in the lab server?

Hi and welcome to the forum.

As you have just installed NR, there won't (or: SHOULDN'T) be any flows.

On the left you will see a list of nodes installed.

Drag them into the main area and then `DEPLOY`.

Next time you load that page, the nodes should then reappear.

## NOTE

That is the basics.

To actually get things _WORKING_ then you need to do a bit more work.

But for example:

get (DRAG) the `INJECT` node, drag it into the main area. Release the mouse LMB.

then _get_ (sorry: DRAG) the `DEBUG` node to the `inject's` right.

Join them with a _WIRE_. LMB (being held down) from the little circle on the `inject` to the little circle on the `debug`.

DEPLOY

Press the _button_ on the `INJECT` node.

You will see a number displayed in the right column.

That is the `timestamp`.

If that works, then you are working.

Now you need to learn the workings of using Node-Red.

thank you for reply and suggestion!  
I understood them well.  
My motivation to post this topic is that the page is NOT rendered correctly due to some errors (I pasted the error page above), so there's no left side bar for me to click (or drag).

On my own laptop (which has no network access limitation), I successfully saw everything like below:

 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/0/3/03f13efbc121e5c86e5ba0c24f121f6bfe725e3f.png)

On one of our lab server (which has network access limitation), I only saw this empty page (with the exactly the same installation files and steps):

 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/3/5/35f9021bc401027d0f3bfcc97638fa1887f1ae79.png)

I am expecting some clues of how to resolve these errors and make the page render correctly.

thank you

I suspect the browser version is too old to support some of the newer syntax.

Here are 3 (of the many) threads with exact same issue....

Is the PC running Windows or Linux?

How do you start Node-red?  
There may be clues in the startup log.  
On Linux you can see this in a terminal window by running node-red-stop and then node-red-start. I don't know the Windows equivalent.

Have you tried a different browser?

As long as it is being maintained. The default browser on Windows Server 2022 is MS Edge (Chromium) which should self-update to the latest version.

IE 11 is also installed on that version of Windows Server as well though so (though it isn't the default) you need to make sure you are using Edge and that the server is fully patched.

Even in a lab, anyone running outdated versions of Windows server is asking for trouble - big trouble. 🙂
