Hello @furkanyildiz2557,

This error happens because the simulated robot is not ready yet. In the top-left corner of the simulation window, you can see some red squares. These indicate that the simulation is not working properly. They should turn green when the simulation is running as expected.

This could be temporary, for example, due to a poor internet connection, or something in your system might be blocking the simulation.

Are those squares always red for you?

Best,

Adding to what @albertoezquerro said, please see the following post for troubleshooting the “red dots problem”, should it persist:

the issue was the VPN. I didn’t know it could create such problems. Thank you !
