I was checking my code with check50 command, then terminal stops working. I closed it and tried to open a new one, but no response. Next, I closed the web and tried to re-logged on but an error message popped up:
Unable to access your workspace
ssh process died with exit code 255
ssh: connect to host docker-gce-ae-224-prod port 38024: No route to host
Can anyone help? Thanks in advance!
