New account, Authentication error (Code: 10000)

Hello i have created a new account and instantly after creating it i have started to recieve Authentication error (Code: 10000) messages everywhere on the website.

I have tried multiple times submiting a support ticked on my account but when i click the submit ticked button im greeted yet again by the 10000 error. I do not know how to proceed to fix this

If you keep getting the error, can you create an Account ticket and share your ticket number here? You can open an Account ticket here, https://dash.cloudflare.com/?to=/:account/support
