Recently updated my IntelliJ IDEA, and the project imported just fine.
Then out of the blue, the gradle refresh fails:

This was unexpected, as literally no problems were happening before this.

Upon clicking the url of the location searched, I get this: [Screenshot]

I have tried manually specifying different gradle versions, Java versions for gradle, and reimported the project several times (deleting the idea project entirely) with the exact same result.
 

Edit:
Probably has something to do with the migration of files.minecraftforge.net/maven to maven.minecraftforge.net

Well, that was anticlimactic.
New build.gradle:
 

buildscript {
    repositories {
        maven { url = 'https://maven.minecraftforge.net' }
//        maven { url = 'https://files.minecraftforge.net/maven' }
        mavenCentral()
    }
    dependencies {
        classpath group: 'net.minecraftforge.gradle', name: 'ForgeGradle', version: '4.1.+', changing: true
    }
}
apply plugin: 'net.minecraftforge.gradle'
// Only edit below this line, the above code adds and enables the necessary things for Forge to be setup.
.
.
.
rest of file as normal

So much for not editing above the line.

BUILD SUCCESSFUL in 14s
