Not opening of the test

Describe your issue

I’m writing Monocept 11 oct test; after completing 1st task my next tasks are not opening i.e., they are showing error of not connecting to the server and tell me to reload the page but after reloading also I am not able to open the task. So please check the error and correct it in time so that I can attend the next tasks and complete my test.
