You're seeing this error because of transient problems on the Application Insights backend, but the error should not be fatal and your app should continue working as expected (albeit with this message being printed).

In the default configuration of the Application Insights SDK for Node.js, communication with the backend is retried - so you should be able to ignore this error and still see telemetry show up in the Azure Portal.

If you've changed the defaults, the setting you'll want to make sure to set is .setUseDiskRetryCaching(true) For example: 

appInsights.setup("key")
    .setUseDiskRetryCaching(true)
    .start()

If you want to suppress messages like this from the SDK you can disable internal logging: (Be aware you'll be suppressing other errors potentially as well)

appInsights.setup("key")
    .setUseDiskRetryCaching(true)
    .setInternalLogging(false, false)
    .start()

If you're curious about the history of this issue, and why it spontaneously occurs, there's a long-running issue on GitHub here: https://github.com/Microsoft/ApplicationInsights-node.js/issues/180
