SocketException on downloading Gradle

[AaronMT]

Hello,

With v2.21.0, I am occasionally seeing this failure to download Gradle. I don't know why this is happening or if there's anything that can be done here, but I am opening a ticket.

The emulator boots, and then fails on downloading Gradle.

Emulator booted.

I am using a Pixel 2, API 28/x86_64 setup in our workflow.

(Un)fortunately, this happens in gradlew and is completely unrelated to android-emulator-runner. Have the same issues doing regular no-emulator builds. Happens in gradlew, happens when downloading through sdkmanager, even saw GitHub checkout failure. Something with GitHub Actions runner networking.
