From the last two contest the "human verification step" got stuck and i was not able to give the contest. I tried to open codeforces from multiple browser but nothing happened. As i opened the website from my mobile phone the verification step passed quickly, is there anything wrong with my pc. Can someone explain what is wrong with this and how can i resolve it.
I had also that problem, it is always be on div 4, and sometimes in div 3. Because of thousands of people submit at the same time
I agree, In today's contest I am also stuck at human verification step several times.
codeforces should look into this.
We also have this type of problem, so we can not do anything with this
i also faced this .
