Cert has expired


I have a HTTP Request node which complains about CERT_HAS_EXPIRED.

The site uses Lets Encrypt but not expired

Any idea how to fix?

Given that the dates shown look valid - I would check the clock on your PC is in sync.

Upgraded Node-Red since it was fairly old and now it seems to work

What version of nodejs were you on?

Nodejs has a baked in list of trusted CA and when LetsEncrypt swapped root CA it would no longer be trusted

Running docker and nodered/node-red-docker:0.20.8-v8
Now running nodered/node-red:3.0.2

Yep, that will be the CA certs expiring in nodejs
