Oculus quest 2 not charging been plugged in for 24 hours

My unit has been plugged in for roughly 24 hours now. It alternates from a red solid light to a red flashing light. I've tried dozens of steps to force charge the unit. Everything from different plugs or charging cables. Cleaning the ports and trying to both soft and hard reset the unit. I am unable to turn the unit on even when plugged in and am at the stage that I would factory reset the unit if I could. Is there anything I can do to resolve the charging issue?
