Launch problem in Vacuum cleaner (firefox, local backend, version 3.1.11)

Hi! I’m trying to launch docker but it doesn’t work, in an hour I have succeeded twice and in the rest of the attempts it gets stuck in “launching 1”. I’ve tried to restart the browser, clear the cache but it doesn’t work either. I’m using Ubuntu 20.04.

launch 2

Hi, we just released a new docker image: jderobot/robotics-academy:3.1.12. Please try with this new version and report if this happens again.
