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

Getting this is 2018.4.22f1, still not fixed.
I have no idea why I'm getting it, but it's positively infuriating to have my console spammed with this error for no particular reason.
