[🐛 Bug]: Relay Node unable to check service status of Appium service.

[biggiethehacker]

What happened?

I have deployed a single relay node that connects to an Appium instance, both deployed in AKS. I have exec'd onto the pod and can confirm that the Appium instance /status endpoint is accessible. However, the relay node is unable to check the service status (see log below).

seluser@appium-android-relay-b5d7577cf-kgjfc:/$ curl -v http://appium-android:4723/status --noproxy '*'
