The BZM - Parallel Controller & Sampler plugin causes SSL errors and RequestAbortedException when executed on a local system with JMeter version 5.4. If the same JMX script is uploaded to BlazeMeter, it executes without errors.
There is a problem with the 0.9 version of the BZM - Parallel Controller & Sampler plugin when used with JMeter versions newer than the 5.2.1 version as documented in the following JMeter bug report: https://bz.apache.org/bugzilla/show_bug.cgi?id=64618
Release : SAAS
Component : BLAZEMETER PERFORMANCE TESTING
To run a JMeter script which uses the BZM - Parallel Controller & Sampler plugin on a local system, use the 5.2.1 version of JMeter.
