Error sending events

Problem

The agent can't connect to the New Relic servers and you see an error like the following in the logs of the agent or forwarder containers:

$
2018-04-09T18:16:35.497195185Z time="2018-04-09T18:16:35Z" level=error 
$
msg="metric sender can't process 1 times" error="Error sending events: 
$
Post https://api.newrelic.com/metrics/events/bulk: 
$
net/http: request canceled (Client.Timeout exceeded while awaiting headers)"

Solution

Depending on the exact nature of the error the message in the logs may differ. To address this problem, see the New Relic networks documentation and the Troubleshooting New Relic infrastructure agent networking issue GitHub page.
