The Pi is not reachable with noVNC from outside of the network



very interesting tutorial.
I have some problems about the paragraph “Accessing The Pi Desktop Using noVNC Remotely”. In detail i’m not able to access to my raspy from the browser. Have I to use noVNC? How? Could you explain better how to configure the noVNC parameters?

Please give us some time to test it and then we’ll reach you back.

Thank you!

#3, can you be more specific about what you tried? What operating system are you using? Raspbian for Robots (did you download it from our site?)?

Are you using NGROK? Have you been able to use ngrok successfully from the command line?

win desktop pc?

I’m using raspbian downloaded here:

Thanks a lot





Everything can be found in the tutorial.

In order to access your Raspberry Pi board with ngrok you need to do the following things.

After you download it, open it and type into the Specify the destination you want to connect to -> Host Name (or IP address) your ngrok address, which in your case is Then add in the Port text-box the port you have: in your case it’s 15786.

Click Open and then enter the usual credentials for your Raspberry Pi.

For VNC Connections

Copy paste the red-encircled text of yours and put it in the browser and then hit enter.
It’s like in the following screenshot:

And then enter the robots1234 password and that’s all.

Thank you!
