How can anyone know what is wrong unless you give a lot more information?

I have a server that im trying to reach out to with websocket node.I have a inject node that is going in websocket out(connect to), and websocket in node that ins connected with debug node.
Under the websocket node i get text that says connected
And everytime i try to inject the msg it disconnects

Select those four nodes and Export to Clipboard. (Ctrl+E or via menus). Then paste the flow here using the technique described in this post - How to share code or flow json.
Then we will be able to see how you have configured them.

What OS/hardware are you running node red on?

What version of node-red?

What version of node.js?

What does the server log show when it disconnects?

10

win10
node.js v15.2.1
node-red v1.2.9

it shows nothing..

11

That is not a recommended version of node.js. It may not be the cause of the problem but I suggest that you go back to 14.x in order to check.
After downgrading you will need to re-install node-red and go into your .node-red folder and run
npm install rebuild

If that doesn't help then can you increase the log level on the server?
