I'm running a test from JMeter sending HTTPS requests to a load balancer that is then distributing the user load across multiple application servers. We have an instance where as the load grows we are seeing
Non HTTP response code: org.apache.http.conn.HttpHostConnectException errors reported in JMeter. In this instance we are not seeing the requests making it to any of the application servers.
In order to isolate where the problem lies (Load Balancer or Load Generator) I was attempting to utilize Wireshark to validate request transmission, but it's unable to provide me with the information due to being HTTPS.
The issue is observed both in a single load generator configuration and JMeter Server configuration with 1 master and 2 load generators. All 3 are using JMeter 5.1.1 and are being hosted on a Windows Server VM.
