TikTok logged me out

Hello,

Yesterday TikTok logged me out of my account. I tried logging back in with the password Ive had for the past 9 years and it said it was the wrong password. So I tried changing it and when I did that it said 'login expired' or 'maximum tries reached'. So I waited until today to try again, and it still says the same thing. I dont know what has happened, I've tried contacting TikTok themselves but they're the worst at replying to complaints. Ive deleted the app and cleared the date from the app itself, I dont know what is left. 

Please help
