Invalid Credentials for Data Source on Scheduled Refresh

Power BI randomly seems to throw errors for "Invalid Credentials" on ODATA sources that I have setup on a scheduled refresh. The credentials have never changed, so I'm not sure why they would ever be invalid. Seems like a bug in the authentication process or storage of the credentials. This causes problems when the scheduled refresh fails several times and then cancels itself, requiring me to reauthenticate. Has anyone else seen this issue?
