JMeter recording - 'ERR_SSL_PROTOCOL_ERROR' and 'Software caused connection abort: socket write error'

Question

I'm new in JMeter and my topic seems to be very similar to another ones already existing. However, it is not - I was trying already all the solutions for the errors that I get and nothing works :/ I have already set up all proxy settings and certificates, and it's working fine (with the same settings) on the other VM. Outside the recording, I can see proper 'No Internet' warning: enter image description here

However, once started recording, there are errors in the console and the front end of the application does not look like originally: enter image description here

Please help! I've already done all the recommendations for clearing caches, SSL, removing files in Windows32 archive and so on...

Answer 1

You should try recording your script using Blazemeter Chrome Extension. Hope, this resolve your issue.

Answer 2

It might be the case there are differences in machines themselves, not in JMeter settings, for example this No Internet message most probably means that the browser is connected to JMeter's proxy server, but JMeter itself cannot connect to the internet.

Try creating a simple manual Test Plan with a single HTTP Request sampler to open http://example.com website. If the request will be successful - you will need to double check your browser and JMeter configuration. However if you get the UnknownHostException instead it may mean that:

1. Networking configuration of the machine is incorrect (it cannot access the Internet)

2. The machine requires an upstream Proxy server in order to be able to access Internet resources so you will need to make JMeter aware of this proxy server by passing appropriate command line arguments to the JMeter startup script:

   jmeter -E https -H my.proxy.server -P 8000 -u username -a password -N localhost
   

   in order to make the changes permanent you can define:

   • http.proxyScheme
   • http.proxyHost
   • http.proxyPort
   • https.proxyHost
   • https.proxyPort

   in system.properties file and http.proxyDomain in user.properties file, check out Apache JMeter Properties Customization Guide for more information on JMeter properties and ways of setting and overriding them
