Power BI Sign up error

[Weka]

Whenever I click the signup or login link it has a browser error:

Bad Request - Request Too Long

---

HTTP Error 400. The size of the request headers is too long.

From here:

https://powerbi.microsoft.com/en-us/get-started/

or here:

https://powerbi.microsoft.com/en-us/landing/signin/

I can't seem to find where to contact support to resolve this issue.
