Cant upgrade Load Balancer plan to add extra origin servers. "Authentication error (Code: 10000)"

I’m trying to upgrade our Load Balancer plan to add extra origin servers and getting “Authentication error (Code: 10000)”.

I can see this is a common issue across the dashboard. I have tried clearing cache, restarting browser, logging out and back in. Accessing site from incognito.

Cheers Ben

@ben.wilkinson2 Did you resolve the issue? I’m having exactly the same problem.
