How to Fix TikTok App Not Working in Android & iOS?

TikTok may not work mainly due to issues with its installation or as a result of network restrictions. The issue is reported on all the TikTok-supported platforms like Android, iOS, Windows, browsers, and emulators (like BlueStacks), etc.

For some, a device’s operating system update triggered the problem. The problem is also reported by people who use a VPN to use TikTok. The issue is noticed when either the app does not launch, does not fetch content, or crashes when doing an action e.g., liking or commenting on a video.

TikTok Not Working

1. Restart your Device and Networking Equipment

Due to an internal glitch, your device or networking equipment may not let the TikTok app access essential online resources. Here, restarting your device and networking equipment may resolve the issue. Before moving on, make sure the TikTok servers are not down

  1. Firstly, exit the TikTok app and remove the app from the recent apps list.
  2. Now launch the TikTok app and check if it is working fine.
  3. If not, power off your device and related network equipment (like a router, Wi-Fi extenders, etc.).
  4. Now, wait for a minute, and then power on the router.
  5. Once the router lights are stable, power on your device and launch TikTok to check if it is working fine.

2. Update TikTok App to the Latest Build 

If the TikTok app is missing the latest patches from the developer, then its incompatibility with the OS may not let the app execute properly and thus cause the problem. Updating the TikTok app to the latest build may resolve the issue. For illustration, we will go through updating the TikTok app on an Android phone.

  1. Open the Google Play Store and search for TikTok.
  2. Now check if a TikTok update is available. If so, tap on the Update button.
    Update the TikTok App
    Update the TikTok App
  3. Once updated, press Open and check if the TikTok’s working problem is cleared.
  4. If not, check if updating the device’s OS to the latest build clears the error.

3. Disable IPv6 in the Router’s Settings 

If TikTok is only not working when using the Wi-Fi or using a particular network (like the office’s Wi-Fi), then the IPv6’s incompatibility with TikTok servers or your device’s configurations could be the root cause of the issue. In this scenario, disabling IPv6 in the router’s settings may resolve the issue. The general guidelines are as under:

  1. Head to the management portal of your router (either through an app or browser) and if required, log in using your credentials.
  2. Now steer to its Settings page and open Advanced Settings.
  3. Then select IPv6 and in the resulting menu, set the dropdown of the Internet Connection Type to Disabled.
    Open the IPv6 Tab in Advanced Settings of Your Router
    Open the IPv6 Tab in Advanced Settings of Your Router
  4. Now save the changes made and restart your router.
    Open the IPv6 Tab in Advanced Settings of Your Router
    Set the Internet Connection Type of IPv6 to Disabled
  5. Then restart your device and upon restart, launch TikTok and check if it is working fine.

4. Re-log into the TikTok App

If TikTok servers fail to authenticate your TikTok session properly, they may not respond properly to the queries from your device, resulting in the problem under discussion. Here, re-logging into TikTok may resolve the issue.

For illustration, we will go through the process for an Android phone, but you can also try this method on other platforms. This method may not be viable for every person facing the problem. Do not forget to keep the credentials available to re-log into the TikTok app.

  1. Launch the TikTok app and switch to its Profile tab.
  2. Now tap on the hamburger menu (near the top right) and open Settings and Privacy.
  3. Then scroll down to the bottom and, afterward, tap on Logout.
    Logout of the TikTok App
    Logout of the TikTok App
  4. Now confirm to log out of the TikTok app and restart your device.
  5. Then launch/log into the TikTok app and check if it is working fine.
  6. If that did not work, then without logging out of the current device, log into TikTok on another device (like another phone or browser on your system) and check if TikTok is working fine on both devices.
  7. If it only works fine on the second device, log out of the first device and like a video on the second device.
  8. Now log into the TikTok app on the first device and check if the issue is resolved. 

5. Reset the TikTok App (Android)

If the cache and data of the TikTok app are corrupt, then the app may fail to load the data and thus essential components might not work. In such a case, resetting the TikTok app or clearing its cache or data may clear the issue.

  1. Launch Settings of your Android phone and head to its Apps.
    Open Apps in the Android Phone Settings
    Open Apps in the Android Phone Settings
  2. Now select TikTok and tap on Force Stop.

In this context, resetting your device’s network settings to the defaults may resolve the issue. Before moving on, make sure to note down the network credentials, proxy settings, VPNs, etc. (things related to networks) as these will be wiped clean from your device.

7. Try Another Network Type/Network or Use a VPN

If there is a network hindrance in TikTok’s communication between your device and TikTok servers which is not letting the app execute properly, then that could also be the root cause of the issue. For example, your ISP is using an APN located in a country where TikTok is banned. Here, trying another network type/network using a VPN may clear the issue.  

  1. Firstly, check if using the mobile data only (after disabling Wi-Fi) or vice versa solves the problem.
  2. If not, check if connecting your device to another network (you can use a hotspot from another phone on a different network where TikTok is working) and using TikTok resolves the issue.
    Enable Hotspot on the iPhone
    Enable Hotspot on the iPhone
  3. If that did not work, download, install, and launch a VPN app.
  4. Now connect it to a country where TikTok is not banned (like Canada) and check if it clears out the TikTok problem.

8. Reinstall the TikTok App

TikTok might also fail to work if its installation is corrupt and the device’s operating system is limiting the execution of the corrupt app components. Here, reinstalling the TikTok app may solve the problem. A point to remember is that you may lose your drafts. Also, keep the login credentials available before reinstalling the TikTok app. For illustration, we will discuss the process of reinstalling the TikTok app on an Android phone.

  12. If that did not work, check if installing TikTok into your phone’s Secure Folder (like on a Samsung phone) clears the error.

9. Disable the Device’s Location and Change its Region

If you have traveled abroad and a change in your location/phone’s region is hindering TikTok’s algorithms, then that may cause TikTok not to work. Moreover, if you are in a banned country, then that could also stop TikTok from running.

Here, disabling the device’s location and changing its region may resolve the issue. In the case of a banned country, you may need a VPN to make it work. For illustration, we will discuss the process for an iPhone but you can use the same technique on other TikTok-supported platforms.

    Remove SIM Card from iPhone
    Remove SIM Card from iPhone
  7. Then power on the iPhone without reinserting the SIM car), launch a VPN app (you may need to install one if not present), and connect it to your desired country (like Canada).
  8. Now install the TikTok app and then launch it to check if its issue is resolved.
