Not a valid URL

When I enter the URL I want to play - https://streaming.radio.co/s1d876459b/listen - it says Not a valid URL. Why? How to make it valid?

Forums:

I found that trying http instead of https makes it work, so this is done.

Now I have another question: how to make a list of URLs?

Hello, I didn't know that ^ means Ctrl. Now I found how to create the URL list, so this bug report may be deleted. Thank you!
