Node update problem

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. 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, from the machine and see what comes back.

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

IPV6, the problem that keeps on giving!
