Tracking home location issue

Hi, i seem to be lost because i have installed home assistant a few days ago and am getting an issue where it wont show my home location with a circle and show my phone battery and if it where charging. i just restarted my raspberry pi and it was working all of a sudden and then it stopped working and has not since it has been a few hours since it started and stopped working. In the IOS application it shows there are x’s next to the IOS component loaded and device tracker component loaded . I do know that it should be working of the bat but it isn’t and just would like to know how to fix it? thanks for future reply’s
