[SOLVED] URL loads in the browser, but not in the terminal (curl or Node.js)

Issue

I want to make a GET request to https://www.bnro.ro/nbrfxrates.xml (the National Bank of Romania) to get the exchange rates for today.

While the XML document loads fine in the browser (tested in Safari and Chrome), it somehow fails in the terminal (checked with Node.js and curl):

$ curl -vL http://www.bnro.ro/nbrfxrates.xml

More details here: https://curl.haxx.se/docs/sslcerts.html

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.

Both, curl and my Node.js app comaplain about the certificate.

In my Node.js script I get this error:

{ Error: unable to verify the first certificate
    at TLSSocket.<anonymous> (_tls_wrap.js:1104:38)
    at emitNone (events.js:105:13)
    at TLSSocket.emit (events.js:207:7)
    at TLSSocket._finishInit (_tls_wrap.js:638:8)
    at TLSWrap.ssl.onhandshakedone (_tls_wrap.js:468:38) code: 'UNABLE_TO_VERIFY_LEAF_SIGNATURE' }

I tried to use the Copy as CURL command option from Chrome, and that does not work either.

Why is this happening? How can it be fixed?


Solution

a missing certificate bundle, read more about it here https://curl.haxx.se/docs/sslcerts.html but the TL;DR is download https://curl.haxx.se/ca/cacert.pem and run 

curl -vL --cacert cacert.pem http://www.bnro.ro/nbrfxrates.xml
