Homepage Widget Request url is https://https//DOMAIN NAME - Chrome

We're trying to run some basic syteline homepages / widgets in Homepages, but each widget fails to load. Upon closer inspection, it seems the problem is that the url already contains 'HTTPS://' in it. If we adjust the source in chrome, can remove the extra 'https://' from the url and the widget functions correctly.


Any advice on how I can fix this error?
