@GENERALNIGHT123 I will quickly summarise what advice EA will offer you for this issue:
1. Turn xbox off an back on,
2. power cycle xbox (hold power button down until it powers off and then unplug the cable at back)
3. uninstall the game,
4. from home page quit the game
5. delete all saved data from every where,
I am still currently waiting a FIX for this is issue, to the point I no longer play BF1 and I now play other shooters that allow me to join servers without a long wait to join servers.
The more annoying things is that BF4 works, quick load times etc.
Does make you wonder what the quality of BF5 is going to be like if they can't fix an issue with BF1 that has been out for years now.
