Sending 3020 Error

Development Tools Cloud Chrome App
1

Hi, I love that the Arduino Create for Education app is free for students now! We keep getting an error when trying to upload to the board (Arduino Uno) on my school chromebook. The error reads "Sending 3020: receiveData timeout after 400ms." Is there any way to avoid this so I can send to the board for more than 0.4 s and actually upload the sketch?

Thanks!

I know nothing about your computer but I will take a SWAG and say the port is not being accessed by your system.
