Hello there.
When i click on the “Log in” button on the “openai.com” site there is oprn another tab with choose: ChatGPT or API. Im click on "ChatGPT" button. There is page with two buttons "Log In" and "Sign up". I click the "log in" button and have white screen. There is no loading or something. Just completely white page. On other device in this networ is ok. In another browser on this PC -- same problem. Im tryied manipulate DNS and clear the DNS cash, tryed to reboot router and check the “hosts” file – nothing help.
It hapens after i delete the browser history with clearing cookies.
Plese help me, i don`t know what to do 
P.S.: I followed all the instuctions from ChatGPT on this theme – it not helps either.
