Can any one help me i am not able to connect with my iPhone device neo load give error like transmission error.
First of all, your Iphone device and NeoLoad machine have to be connected to the same network like a WIFI network.
Then make sure that there's no firewall started on the NeoLoad machine. To check the connectivity between the Iphone and NeoLoad, you can simply start a recording on NeoLoad side, change the proxy settings on your Iphone to "<NL_IP>:8090".
Then launch Safari on the Iphone and try to connect to "http://<NL_IP>:8090".
You should reach a page with the "Logo NeoLoad recording" message. If not then you probably have a firewall that is blocking the communication.
If it works then you should be able to record Safari traffic.
