Dear Gustaf,
It did help me to remind and  review my own code to assure that it was properly 
written. I grabbed the code from 
https://naviserver.sourceforge.io/n/naviserver/files/ns_http.html#5 
<https://naviserver.sourceforge.io/n/naviserver/files/ns_http.html#5>
Plus, I switched to ns_base40encode. Before I was using Openacs [base64::encode 
“${client}:${secret}"]
I've used the very first, basic and simple example (i.e. http queue and http 
wait), and still, I get the same logs.
https://evex.co/paypal-checkout <https://evex.co/paypal-checkout>


Notice: HTTP 
 status 0 time 0:215139 headers d5 body {} https {sslversion TLSv1.2 cipher 
AES256-SHA256}



I’m able to change credentials whenever I want to get 400 error to return. That 
means the credentials passed in the header were properly assigned.
Even though I agree I need to talk to the guys on PayPal, in case I missed any 
parameter to allow connectivity on their side.


Notice: HttpTaskRecv: connection probably closed by server (url 
https://api.sandbox.paypal.com/v1/oauth2/token 
<https://api.sandbox.paypal.com/v1/oauth2/token>)



Best wishes,
I
