Having trouble loading JS CDN

Question

Hey Guys,
I attached a script tag containing the CDN to date-fns JS library. For some reason, the library won't load in Sololearn. When I'm working in my text editor and open the page in chrome everything works just fine. Not sure what's happening. Any ideas to resolve the issue?
Thanks in advance for any help!
