Hi,
The node-Red update is carried out normally but I get this message when I update the nodes:

I notice that I do not have access to the server and using a Unif router, do I need a special eport redirection or Firewall rule?

Hi @Ives25
`ENETUNREACH` is host is unreachable, in this case [registry.npmjs.org](http://registry.npmjs.org). This, does not require any special approach to access.
What I am noticing however, is that the machine you are using, seems to be trying to connect to an IPv6 address, so maybe as a test, disable IPv6, and try again.
if still does not work, then you need to check your local network for routing issues, such as proxies/DNS filtering etc etc.
try and ping [registry.npmjs.org](http://registry.npmjs.org), from the machine and see what comes back.

That's the problem, by removing IPV6 it works. Thank you very much for your help !
