I have jmeter version 5.2.1. I have recorded a blaze meter script. I opened jmeter from command prompt using the below syntax (jmeter -H proxy -P 80 -u username -a password)
Then on the GUI, I have given the proxy details in HTTPRequestDefault, also at the test level as shown in the screenshot.
But still I keep getting Response code:407 Response message:Proxy Authentication Required
