Hi,

I can't really tell If I have done something wrong, but it seems to be a problem with an intermediate certificate in the chain of letsencrypt.
So I am using keycloak, with an letsencrypt certificate and I am getting the following error:

["ERROR","2024-10-19T09:13:27.030Z","CHALLENGE_RESPONSE_ACTION_ERROR",{"error":{"stack":"Error: unable to verify the first certificate\n at TLSSocket.onConnectSecure (node:_tls_wrap:1674:34)\n at TLSSocket.emit (node:events:519:28)\n at TLSSocket._finishInit (node:_tls_wrap:1085:8)\n at ssl.onhandshakedone (node:_tls_wrap:871:12)","message":"unable to verify the first certificate","code":"UNABLE_TO_VERIFY_LEAF_SIGNATURE"}}]

A search suggested this package to be installed and executed: https://git.coolaj86.com/coolaj86/ssl-root-cas.js

(for testing purposes one can set: export NODE_TLS_REJECT_UNAUTHORIZED="0")

But I can't really tell where and how to incorporate it.
