mBots no longer able upload to Arduino


#1

I have been using 6 mBots for the last 2 years and they were running fine with editor.makeblock.com until 2 weeks ago. Now we are having constant issues.

In the past we could connect through USB.
Switch over to <>code/upload
Update Firmware.
Choose code blocks to run while connected via USB or Upload to Arduino.

Now students get this Error:
Compiled Failed
Picked up JAVA_TOOL_OPTIONS:
Exception in thread “main” java.awt.AWTError: Can’t connect to X11 Window server using “:1.0” as the value of the DISPLAY variable…

Note: The mbot is turned on. I have disconnected and reconnected. This is happening with all our mBots and all Chromebooks. This was not an issue with any mBot or CB before May 1, 2019.

I have tried mLink (https://ide.makeblock.com/#/). The mBot will connect and run a code will connected to the USB, but fails to update or upload.

My entire robotics program has come to a standstill due to this error. Any help is greatly appreciated. Thanks.
