"Connection Lost" error when opening simulation

Hi,
Simumatik has recently started giving the error “Connection Lost” when I open a simulation, and it keeps showing up even if I press “Reconnect” or restart the local workspace. Here I leave the screenshot.
Thanks.

Hi Urtzi!
Could you check if there is any error in the browser log?
You can also send us a screenshot or copy the logs in the workspace. Check this address in another tab of your browser: http://localhost:4880/logs
