After following instructions in readme and executing remotedebug_ios_webkit_adapter --port=9000 in windows powershell I get the following error:

Same issue

[RealDyllon]

Had the same issue. Once I switched to port 9222, it worked fine

remotedebug_ios_webkit_adapter --port=9222

[stefan-reloyalty]

@RealDyllon Oh, you saved my day, thanks a lot!

This CLI will listen to two ports, one is the port you specified, which is 9000 in this case. And another port is the port you specified +100, which will be 9100. But unfortunately, in my computer, the LGHub software used this port. Therefore, the CLI tool always get a wrong response and then crash.

Same issue when trying to start without giving a port that tries to start with port 9000. Startng with
remotedebug_ios_webkit_adapter --port=9222
Starts and you can list your webpages, but then you end up in next problems where you just see a blank page:
#181
#180
