Hi,  
having a strange issue with node red. every time i try to deploy the flow my node red get stuck and only way to fix this is restart the node red.  
I got a pc with 64gb ram and AMD Ryzen 4000 processor ( no other apps running).  
any idea what might be going on.

Thanks

Mmm..

If this isn't getting stuck during start up, there maybe an installed module (node) that is hooking into the `deploy` event. Node RED nodes have the ability to hook in to the `deploy` process.

[https://nodered.org/docs/api/ui/events/](https://nodered.org/docs/api/ui/events/)

it could be that such node is doing so, and is having problems completing its operation.  
I say the above, as its strange why it is not happening at start up.

maybe disable some select nodes, and then try a 2nd deploy after, if after you are able to get a smooth deploy, you have found the culprit.

you could also change the deploy scope - say only modified nodes, so a full deploy isn't executed.

In a terminal window, stop NR then start it again. Then open a browser window and make a minor change and do a deploy.  
Go back to the terminal window and copy the log from the start up to it's end and paste it in a reply.

Also, did you add a new node to your flow just before this started to happen?

Your flow credentials file is encrypted using a system-generated key.

If the system-generated key is lost for any reason, your credentials  
file will not be recoverable, you will have to delete it and re-enter  
your credentials.

## You should set your own key using the 'credentialSecret' option in your settings file. Node-RED will then re-encrypt your credentials file using your chosen key the next time you deploy a change.

Same flow works find on old pc as well as on RPI. this new pc does have windows 11( i wish i can go back in time and revert back to win 10 ) .

There is clearly a node, that is doing something when the flow is being restarted.

![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/4/d/4d35229b7d22e088900395aaea86c1a0e3ef51c1.png)

Whatever it is doing, it's getting stuck, which is causing the deploy to grind to a halt.  
Disable some of your nodes (maybe some config nodes also), redeploy (twice) and see if it suddenly behaves correctly.

or set the deploy method, to only deploy changed nodes.

you mention its fine on other systems?  
are these system using the same versions of your installed nodes?

if so, something environmental is affecting the close routines of the troublesome node.

You will need to isolate your installed nodes to find out what node is halting the deploy process.
