Unable to get the API Response from darksky API, the response always goes to onFailure

I have copied the code from the video; however, I am not able to get the JSON response in my logcat. I added a log message in my onFailure and I think the code always goes to the onFailure method. Not too sure why I can't connect to the API, I am pretty sure my URL is correct too as I tried simply copying and pasting from the website too.

I tried adding android:usesCleartextTraffic="true" to my AndroidManifest.xml and it worked

Thank you Clara! Lifesaver!
