Error: I couldn’t find any feeds at <https://example.com/> [HTTP request error: :]. Try another URL
The best solution for you will depend on details about your own hosting situation — in particular, what version of WordPress you are using FeedWordPress with, and whether or not you are able to install new PHP modules on your web host, or, if not, whether or not you have someone who is willing to install new PHP modules for you. Unfortunately it’s not likely to be something that FeedWordPress itself can fix. But I have made some updates so that FeedWordPress will, at least, provide some more useful diagnostic information — which may help you figure out what needs to be done, or which will hep me help you figure it out, if you send the diagnostic information to me along with your support request.
