Caused by: java.lang.NumberFormatException: For input string: "your_proxy_port"

JMeter expects the proxy port to be a number, if you copied and pasted the JMeter command-line arguments or system.properties and they contain your_proxy_port - either remove the relevant line(s) or update it to match your proxy server port if you're using the proxy for accessing the Internet.

The relevant command line argument is -P and the properties are http.proxyPort and https.proxyPort
