Unable to detect changes - SSH to Git on Azure

[Chris Bradshaw]

I'm periodically getting "unable to detect changes" to my Git repo via SSH. Its only occasional, and mostly overnight. During my working hours I get one or two throughout the day. Overnight there might be 30-40 notifications. 

I'm trying to interpret the error below to find out if this is a network/infrastructure issue or my configuration. As I say, this works most of the time. 

I find it odd that the git ls-remote is trying to connect to 127.0.0.1. Is the network disconnected?

Is there a notification I can modify to make this report less.
