There a issue regarding to how moodle and vpl works. When the student or the teacher tries to execute a VPL activity it happen in two phases

1. Send the activity to moodle. Return a websocket with the url to the jail to track the process of the execution
2. The browser tries to connect to the jail.

However, the browser cant reach the jail URL because it returns a docker internal IP.

To resolve this issue, you need to ensure your PC can reach the jail.

1. Open the file /etc/hosts/
2. Add to the end of document the next line 127.0.0.1 jail
3. Flush the dns cache sudo dscacheutil -flushcache

To test all is ok, just open the browser and open http://jail:$JAIL_PORT/OK
