got these errors on submitting in Break-the-server in first 5 minutes only
every other submission was giving an error
and after that u will be logged out.
Did you get an alert/popup after getting logged out?
and what did it say?
Why does this ping thing never works with CodeChef? and yeah it does works with diff websites like codeforces, etc.
We have disabled it. How does it benefit you, had we enabled it?
Probably because of a firewall which filters the request type and only fulfills HTTP requests.
