Websocket Read Time Out when using wss protocol

[George Vrachliotis]

Hi Peter,

I am getting a read time out error when trying to setup a new connection using wss. I tried the same wss conection setup request via browser websocket client and via Zaleski’s websocket sampler and in both cases I was able to setup a new wss connection. I have check all networking between my jmeter machine and websocket server and disabled firewalls but still I am not able to establish a new wss connection using your plugin. Any ideas ?

PS: I usually use ws:// which works flawlessly, however test environment in the test I am currently running requires wss://

Can you enable debug logging (see readme.md) and attach the relevant part (when the ws connection is being setup)?

Hi Peter,

thanks for your reply. I have attached 3 screenshots, including the logs as well as opening the same websocket connection via chrome plugin in the same machine.

Can you run JMeter with -Djavax.net.debug=ssl,handshake ? This will generate an awful lot of TLS debug logging to standard out, but at least we can (hopefully) see what happens on TLS level. If that is somehow inconvenient, a WireShark capture would also do the trick.
