Continuing the discussion from Help with Infrastructure Install Failing:
I have installed the NR Infra agent for Windows on 15 servers across 2 DCs. As of right now, only 4 of the agents are communicating with NR.
Manually starting the newrelic-infra.exe app shows the following errors on the other servers:
time="2018-06-07T17:53:08-04:00" level=warning msg="network error waiting for endpoint, retrying" error="Head https://infra-api.newrelic.com: x509: certificate signed by unknown authority"
Following the troubleshooting above, I did find on my working servers the GeoTrust Root CA cert. I exported and imported that from the working to a non-working server (Trusted Root Certification Authorities Store). However, I am still getting the same error.
All of these servers are in the same GPO/Security Posture and should be working.
Running a request in PowerShell using the GetResponse() method of [System.Net.WebRequest] also errors from this server:
"The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel."
Is this still the correct certificate to use? If so, are there further troubleshooting/remediation steps I can take?
