TikTok Login Error Recovery Demand

I am unable to log in to either of my TikTok accounts. It says permissions are not granted and that there is no internet connection. I cannot log in using my Facebook connection either. This issue needs to be resolved urgently, as it has happened to me before.
My internet is working, but it keeps saying there is a network problem, permissions cannot be granted, and providing different error messages each time. I have tried various troubleshooting steps, but nothing seems to fix the problem.
I am frustrated that I cannot access my TikTok accounts due to these persistent login issues. I rely on TikTok for content creation and engagement with my followers. This inability to log in is hindering my ability to use the platform effectively. I hope TikTok can investigate this problem and provide a solution soon.
