I had the same issue after install DragIt environment. It seems remote_control app and DragIt working on the same port - 8000. I just changed that file on my RaspberryPi '''

~/SunFounder_picar-v/remote_control/start

8000 -> 9000 And start that server again.

Now remote_control app via browser works on :9000 port
Dragit on:8000,
Camera streaming working on :8080

What is hapening is that, you run the server once, and when you closed it, it didn't free the 8000 port, or simply that another application is running on that port. What you can do is either :

Change the port as mentioned by @Gaploid OR
Kill the previous process that is still holding the 8000 port by running sudo lsof -i:8000, you will have the PID ( or Process ID ), then take that PID and use it with kill command as follows : sudo kill -9 <PID>

Hi sir , Thanks for contacting us. Could you please provide us your order number first? Which shopping platform did you get it? A short video or some pictures of the issues could be much more helpful. Our staff will contact you later to help with that.

Best Regards,
