Because the company's network management restricts the traffic connected to the Tik Tok server on the router to ensure the stability and security of the network and the work efficiency of employees. You can try the following methods:

1. Modify the settings of the router and add the port number or IP of Tik Tok to the white list of the router, so that the traffic of Tik Tok will not be blocked. However, this may require you to have administrative rights on the router or apply to the network administrator.

2. Modify the mobile phone network settings and add the port number or IP of Tik Tok to the proxy server address of mobile phone wifi, so that Tik Tok traffic will not be blocked. But this may require knowing the address of available proxy servers or installing professional proxy software.

3. Use other wireless networks, such as 4G networks or other wifi hotspots, so that the traffic of Tik Tok will not be blocked. But this may consume mobile phone traffic or other expenses.
