Jmeter - Non HTTP response code: org.apache.http.conn.HttpHostConnectException is observed on trying to record a script for 1 user

Question

I am trying to record a login scenario for my application built using Blazor technology through Templates (File > Templates > Recording) for a single user. I see that few of the initial sampler results are successful and then I see the below error in View Results Tree. Error is constant on trying many times.

In the logs, I see errror in

Line 2: 2021-01-12 09:34:16,562 ERROR f.configuration: DefaultObjectWrapper.incompatibleImprovements was set to the object returned by Configuration.getVersion(). That defeats the purpose of incompatibleImprovements, and makes upgrading FreeMarker a potentially breaking change. Also, this probably won't be allowed starting from 2.4.0. Instead, set incompatibleImprovements to the highest concrete version that's known to be compatible with your application.

NOTE :

I have tried recording using the Non HTTP Script Recorder too - same issue.

I see this issue when application is launched on a test server with no internet connection.

I see this issue when the application is hosted locally on the same test server.

Also in UI - Page contents do not load and login page is displayed as a blank page with only the page title and page url as expected.

The application URL is of the format https://abcd.com:1234/login

I have updated the port number in JMeter and Firefox browser as 8888

Root CA certificate is added.

I see the same issue even after increasing timeout to 60000 in HTTP Request defaults

Answer 1

Looking into the push.services.mozilla.com hostname it appears that JMeter catches requests to Firefox Web Push notifications service (allowing websites to send notifications to you)

I don't think you should be recording these requests (unless you're explicitly testing them) so you should add this push.services.mozilla.com to "URL Patterns to Exclude" section of the HTTP(S) Test Script Recorder

More information: Excluding Domains from the Load Test

You should repeat the exercise for all the requests to/from 3rd-party domains if any so your test scope would be limited to your system under test only
