Error in submitting my code

Hi everyone,

I write code, build and get any errors or feedback. I don’t know whether it is wrong or right.
However, when I submitted my code, I got the error above.

Coud you pld help me.

Sorry that no-one responded to your question at the time. Are you still having this issue? Note that a 403 error most likely indicates some kind of an IT problem: some proxy or firewall must be blocking the access to the grader. If you are still having this issue, my suggestion would be to try it again from a different network. E.g. if you are at work or school, try from home or from a public WiFi at a coffee shop or library and see if that makes a difference.
