Answer 1

For those that have https support but still get an error similar to below

[curl] 1: Protocol %20https not supported or disabled in libcurl [url] %20https://www.example.com/%20

Ensure that the URL is valid

• Try on a basic URL such as https://www.example.com
• Check your URLs and make sure no spaces at start/end of URL (as shown above as %20)
• Check for characters in your URL likely to break the curl request
