In a Windows Server 2019 environment and curl 8.4.0 (Windows) libcurl/8.4.0 Schannel WinIDN
Trying post request (using Postman) from another computer. Getting the following error: "cURL Error #: SSL certificate problem: self signed certificate in certificate chain" The source(host) and destination(https://api.usps.com/) both have valid certificates and CAs and intermediary CAs. There's nothing self signed.Ours (host/source) are from DigiCert.
I've tried setting CURLOPT_CAINFO and CURLOPT_CAPATH, doesn't change the behavior.
Any suggestions/ideas are welcome.
