org.apache.http.conn.HttpHostConnectException with jMeter

Question

I'm getting this org.apache.http.conn.HttpHostConnectException exception in my jMeter script which I'm unable to debug.

• Test server is successfully able to connect to my application urls (https://apac1.onesourcetax.com and https://emea1.onesourcetax.com)
• jMeter script is successfully able to connect to EMEA1 but unable to connect to APAC1 (HttpHostConnectException exception)
• I wanted to compare between what requests jMeter is sending vs what Chrome browser is sending... so I enabled fiddler proxy inside my jMeter script and guess what?? jMeter script is able to connect to APAC1 when sending requests thru Fiddler proxy (localhost:8888)

Does anyone know whats going on here?

Answer 1

I cannot reproduce your issue using latest JMeter 5.2.1:

So my expectation is that it is something environmental.

I would recommend the following troubleshooting steps:

1. It might be the case the HTTP connect timeout it too low and if it takes some time to establish the connection from your location to the server in APAC region JMeter might close the connection if it doesn't receive anything from the server. You can try increasing the Connect Timeout, the setting lives under "Advanced" tab of the HTTP Request sampler (or even better HTTP Request Defaults)

   

2. You can get extra information on outgoing requests and incoming responses by enabling debug logging for JMeter, the level of details as at my first screenshot you can get by adding the next lines to log4j2.xml file (lives in "bin" folder of your JMeter installation):

   <Logger name="org.apache.http" level="debug" />
   <Logger name="org.apache.http.wire" level="debug" /> 
   

   JMeter restart will be required to pick up the changes.
