There are a few possible reasons why TikTok may not be working on your network. First, if you are using a shared connection such as at school, work, or a public hotspot, it is possible that other users are using the same bandwidth to access TikTok. This can cause significant slowdown or even prevent TikTok from loading altogether. If you are using an unstable or low-speed connection, this could also be affecting how well TikTok works. Finally, some routers may interfere with the functionality of TikTok. In order to troubleshoot these issues, you'll need to contact your router manufacturer for help.
