Nativescript-plugin-firebase: Could not resolve io.fabric.tools:gradle:1.26.1.

I have the app working on my Windows 10 machine, but wanted to run both Android and IOS at the same time, so I got a Mac and began porting over the app. tns doctor is returning that everything is OK, but I keep getting this error when trying to run android:

Hi, did you try opening https://maven.fabric.io/public/io/fabric/tools/gradle/1.26.1/gradle-1.26.1.pom in a browser or on a different machine? Your device logs it can't access the URL, but it seems to be available just fine.

Thanks, this led me down the right track. I was running a pihole that was preventing this from being reached. Somehow it worked from my Windows machine, but not my Mac. I disabled, the pihole and it worked.
