Hi @kerrya
I test with your names, but it shows no error.
From this article, it is said that you cannot connect to the same organisation multiple times, as it will affect the scheduled refresh.
Please check which situation you meet.
You may need clear the web browser cash, then reopen the Power BI.
Best Regards
Maggie
