I am trying to record the URL http://127.0.0.1:1080/example.htm.?
But this URL is not launching while recording, I even tried to override the port 1080 in the browsers setting as well as in Neoload(Preference tab)
By default, the loopback address will bypass the proxy. You should try with the IP or hostname in the URL. There's no need to change the default proxy port of NeoLoad. 8090 should still be fine here.
