Have you tried to disable any virus and/or spyware programs? What platform are you using? Is this a new device you're trying to launch on?

try

1. re-charge the robot 2- disconnect the anti-virus
2. re-set the network 4.connect to the wifi that is Ezb4-----
3. then in EZ- Builder scan for correct ip, then connect to your robot

Two Windows 10  pc and one lap top ARC software launches fine if connected to internet. If i'm out of wifi range or not connected to ethernet program wont even launch ,that's b4 i even try to connect to ezb. Wow that's strange if its working fine for others with internet disconnected !.

We've noticed that a bit ago and have a fix for it - we have ARC being re-written for a huge update which makes little tweaks like this challenging. I'll release something this week to fix that

Thankyou This my EZB Dino 16m X 3m high Is this the biggest ezb project ever will keep updated

Neat, I hope you keep updated on this project with pictures and video.

Probable not the neatest job around, Dino moves tail ,lungs, neck and head, tongue, tip of tongue, eyes, eyelids breaths in/out nose with air  boss speakers in head. this is probable wrong sight for posts. runs on dell laptop.
