I can´t start chat gpt plus

Hi, I can´t sign in in my ChatGPT plus account, I have not changed my email or password and all the recommended things, clear cache, try another browser etc. I have done, nothing, funny thing is when I should prove that I am human, I answered all the questions correct, the system says, ok, you are human, and start again with the test. What’s wrong, has anyone an idea?
