Salve a tutti, non ho mai scritto su questo blog e quindi vi prego di perdonarmi se sbaglio qualcosa.  
Da poco ho iniziato ad usare Node-red e non sono molto esperto. Da circa 2 mesi ho installato e usato node-red-contrib-ewelink-copy e ha funzionato sempre bene. da qualche giorno non riesco più ad usare nessuno dei nodi in quanto sia il pc che il Raspberry mi vanno in crash: si scollegano dal server e fermano il programma con **error 403**. Con il comando _Node-red -safe_ ho disinstallato dalla palette e ho provato a rimetterlo di nuovo, ma il problema si ripete. L'app Ewelink funziona bene e i comandi rispondono.  
Potete aiutarmi?  
Grazie

Mario

Welcome to the forum Mario, you will be more likely to get help here if you post in English. I have translated your post for you.

_Hi everyone, I have never written on this blog so please forgive me if I do something wrong._  
_I have recently started using Node-red and I am not very experienced. I have installed and used node-red-contrib-ewelink-copy for about 2 months and it has always worked well. For a few days I have not been able to use any of the nodes because both the PC and the Raspberry crash: they disconnect from the server and stop the program with **error 403.** With the command Node-red -safe I uninstalled from the palette and tried to put it back again, but the problem occurs again. The Ewelink app works well and the commands respond._  
_Can you help me?_  
_Thanks_

_Mario_

Assuming that you installed node-red on the pi using the recommended method ([Running on Raspberry Pi : Node-RED](https://nodered.org/docs/getting-started/raspberrypi)) then start node-red using  
`node-red-start`  
and post what that command shows here. Copy/paste please, not screenshot.

Good morning Colin and thank you for the help you are giving me.  
The installation was done following the recommended method and it worked perfectly for about 4 months.  
I started now with the command you recommended and it gives me this error then the program closes:  
_19 Aug 15:15:06 - [error] UnhandledPromiseRejection: This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch().

I also tried to change ewelink account but the result is identical.  
Thank you.

I'm sorry, but I can't post the reply as the blog gives me an error because I can't post more than 2 messages. I'll try again later or tomorrow.

I had intended to just post the error message.  
There he is:

I don't recognise that message. Do you know what that is about?

Something is using oauth authorisation. Do you know what that is?

Another thought, if you have not already done so, check in Manage Palette that all installed nodes are on the latest versions.

Thanks for the reply.  
Remote-access is used to manage the dashboard on the mobile phone display.  
The nodes are updated to the latest version.  
""error":403,"msg":"Sign:oauthClient enable invalid"}"  
it only appears when I log in to the ewelink account. Then the system crashes and I have to uninstall the Ewelink nodes with Node-red -safe and restart.  
This happens on both the Raspberry Pi4 and Windows. I think it's a Node-red error in managing Ewelink. Do you have any recent information on this?

You could look at some of the other ewelink nodes, this one seem more current e.g. in relation to the oauth 2 issue.

Thanks for the advice. I also tried with another account but the result doesn't change. I will do more tests or I will give up on using this node.  
Thank you for the time you dedicated to me.
