On install Azure.Functions.Cli.win-x64.2.1.748.zip -> Error: self signed certificate

[orlstefano]

Hi,

I've tried to install azure-functions-core-tools on my Windows Dev Machine.
I've used this command:
npm i -g azure-functions-core-tools --unsafe-perm true

but, at least I've recived the error below.
Could you help me, please?

Thanks, Stefano.

hmm, are you able to access that link https://functionscdn.azureedge.net from your machine? do you get an error in your browser?

That's just using the *.azureedge.net ssl cert which has this chain

Baltimore CyberTrust Root
|---> Microsoft IT TLS CA 2
     |----> *.azureedge.net

Nothing there is self-signed as far as I know. What version of Windows are you running?

You can see more details about that ssl cert here https://www.ssllabs.com/ssltest/analyze.html?d=functionscdn.azureedge.net&s=72.21.81.200
