Failing to recognize a Web server

[igarrido]

Hello,

After updating the fingerprint file with a custom signature and running 'example.htm', I got the following error message:

WebSocket connection to 'ws://192.168.0.23/318869b9-5f94-2a3c-fb65-ae2b132dc4d5' failed: Error during WebSocket handshake: Unexpected response code: 404

As a further test, I modified the Sonar.js file and replaced the function 'sonar.generate_random_id()' for a static string, in order to obtain a 200 HTTP response code rather than a 404 and I obtained the following error message:

WebSocket connection to 'ws://192.168.0.23/exploitable_script.php' failed: Error during WebSocket handshake: Unexpected response code: 200

Thoughts?

Did you figure out why that is the case? I am having a similar issue. Solved, see other issue for detail.
