UnityWebRequest fails to verify certificate when "Let's Encrypt Authority X1" certificate is present in system trust store
Reproduction steps:
1. Open Certificate Manager (In Windows, search for "Manage user certificates" in the Start menu)
2. If present, delete Let's Encrypt Authority X3 certificate under "Current User\Intermediate Certification Authorities\Certificates"
3. If not present, install the Let's Encrypt Authority X1 certificate attached below
4. Open the attached project (case_1215665.zip)
5. Enter Play Mode
Expected result: WebRequest is successful and data is fetched
Actual result: The error "Curl error 51: Cert verify failed: UNITYTLS_X509VERIFY_FLAG_NOT_TRUSTED" is thrown and no data is fetched
