Log in fail from CentOs/Firefox

[API USER]

I am trying to log in from a CentOs VM, using Firefox and I am getting this error:

Hmm... We're having trouble logging you in.

We're having trouble logging you in. There seems to be an issue with your identity provider. Wait a few moments, then try again.

Try logging in again

I know the user name/password is good, as I tested it from my Mac laptop

Hi @API USER 

Can you try clearing your cache & cookies and try again? Also see if trying with an incognito window helps?

I tried both and no success. I also refreshed the browser (Firefox).
The URL with the error message is:

I ended up using an Ubuntu desktop and it worked well, no issues.
