Can't Authenticate with credentials provided after email domain changed

Hello Anonymous.
Thanks for your response. 
Just found out more info.
Since my email domain changed in the company that sharepoint contents in power query does not work (it worked just fine previously). Sharpoint files works. Is there anything I could change in sharepoint so sharepoint contents works again?
I have several reports and was trying to avoid having to change the source code in power query in all of them.
