Network connection problem: uploading works requires a stable network connection. If the network signal is unstable or the network connection is not good, uploading the work may fail.
Work format: Tik Tok only supports specific work formats. If the uploaded work is not in the correct format, the upload may fail.
Size of works: Tik Tok has restrictions on the size of uploaded works. If the size of the uploaded work exceeds the limit, the upload may also fail.
Tik Tok's server problem: Tik Tok's server may be out of order or under maintenance. If there is something wrong with the server when uploading the work, the upload may also fail.
If uploading the work fails, you can try to upload it again, or check the network connection, work format, work size and other issues. If many attempts to upload still fail, it is recommended to contact Tik Tok customer service for help.
