Network Error When Changing to a New Screen

I am currently developing a project, that for some reason keeps disconnecting whenever I change to a new screen. No matter what I try, I can't fix it. This is what it shows when I disconnect.

Does anyone know what the problem is or have any idea why this might be happening? Thanks.

Please show your relevant blocks (the ones that are switching screens in particular) and anything you may have in the initialise blocks for the screens you are switching to.

Are you switching screens correctly ?

Use different screens wisely

If you decided to use different screens, then you should switch them correctly, else you will run out of memory after a while...

Thank you. I will try these out.

Sucede cuando vence el tiempo de conexión del codigo QR, se soluciona volviendolo a conectar.

Thank you. I got everything figured out and working. :slightly_smiling_face:
