Tiktok says “Unable to authorize”

So I took a break from Tiktok for a week or so and when I opened it, it wasn’t loading and said “Unable to connect to internet” so I deleted the app and I opened it and it was stuck on the opening page as seen on the photo. I closed it and went back in. I tried signing in but every single option led to the message “unable to authorize” When I pressed the question mark it said “unable to connect to internet” I’ve deleted and re-downloaded the app multiple times, I have a stable WiFi connection, and I can sign into my tiktok account on other devices but not my phone. This has been going on for about two weeks.
