How to resolve Mubi App Not Working on LG Smart TV ? 

1. Ensure That Your LG TV Is Compatible With Mubi

LG smart TV models from 2016 or later, which run webOS, are compatible with the Mubi app. To find out the year of your LG TV, check the model number in the system menu or on a sticker at the back of the device. Further instructions can be found here.

If your LG TV is from before 2016, you will have to decide between buying a new TV or adding a streaming stick. The latter being the more cost-effective and simpler choice.

Mubi can be enjoyed on any TV, regardless of whether it is smart or not, by connecting either a Fire TV Stick or a Roku streaming stick. Both sticks are user-friendly and offer access to all the popular streaming services. 


2. Restart or Power Cycle Your LG TV

Random software issues with apps can be solved by the classic "turn it off and on again" approach that is applicable to most software problems.

When you press the power button on your LG webOS TV, it will not actually reboot. It will simply enter standby mode, which allows it to turn on more quickly. Although this may be convenient, it can also lead to the accumulation of software bugs over time.

To reboot your LG TV fully:

  • Unplug it from the wall socket.
  • Hold the power button on the TV for a minimum of 60 seconds.
  • Then plug it into the outlet again.


Have another go with Mubi app. It's often helpful to restart the TV if you've encountered a bug; the instructions should be kept handy.


3. Determine Your Internet Speed

Buffering problems with Mubi and other streaming services can be caused by slow internet speeds, and the most severe circumstances may lead to the inability to connect to the Mubi servers.

To conduct an internet speed test on your computer or phone, make sure the device is linked to the same network as your TV. Additionally, ensure that mobile data is turned off and your phone is only connected to a Wi-Fi network.

For standard streaming, you should have a minimum of 3–4 Mbps, and for HD, 5–8 Mbps. Anything slower than that and you'll need to take the below action:

  • Investigate possible sources of interference (e.g., excessive walls between your router and television). 
  • Reboot your router and modem (check the following tip). 
  • Contact your internet provider to determine if there are any network issues or if an upgrade is essential.


4. Reboot your router and modem

Don't immediately assume that the problem with your TV or the Mubi app. Sometimes, the issue can be traced back to your local Wi-Fi network.

Instead of troubleshooting each network issue separately, it's more convenient to restart the entire network and check if that resolves all the problems. It's recommended to do this once a month to maintain optimal network performance.

Before proceeding, make sure that nobody in your home is actively using the internet. This process will temporarily disconnect all network and internet connections for approximately five minutes during the reboot.

To start:

  • Unplug both the power cable from your router and modem. 
  • Wait for 30 seconds before plugging them back in. 
  • After that, give the modem and router a few minutes to boot up.


Try launching the Mubi app once your TV is back on the network. If you found that your network speed was slow during your test, now would be a good time to run another one. Restarting your router can sometimes provide a temporary boost to your speeds, but it may not address all underlying issues.


5. Perform LG TV Firmware Update

Similar to app updates, firmware updates can often resolve issues with your TV apps.

LG smart TVs automatically update their firmware, but you have the option to manually prompt an update if needed. Forcing a manual update typically isn’t required, but it provides a safeguard in case the automatic update gets disabled or experiences an error without notifying you.


If you need to update the firmware on your LG TV:

  • Navigate to the Settings menu.
  • Select All Settings
  • From there, click on General.
  • Then Scroll down to About This TV
  • Finally, select Check For Updates and follow the on-screen instructions to download and install any available updates.

Uninstalling and reinstalling the app is an easier way to fix app-related issues than manually clearing the cache on LG TVs. 

In order to reinstall Mubi, you must first remove the app and then install it again.


To delete the Mubi app:
  • Use your remote to go to Home, locate the Mubi app.
  • Press and hold the app icon.

  • Click on About this TV.
  • Ensure Accept All has been chosen in the User Agreements.

Most streaming content and some streaming applications are limited based on geographical location.

Streaming apps like Mubi often confirm the user's location by connecting to their TV, and this is especially true for LG TVs which have their own built-in location setting.

  • Using your remote, access the Settings.
  • Next, select the General tab.
  • Click System.
  • Select Location.
  • Update the zip code to your current address if it's inaccurate.



9. Turn Off Your VPN if applicable

This step only applies to those who use a virtual private network (VPN). If you are unfamiliar with VPNs, then it is likely that you do not have one.

If you're using a VPN that Mubi has managed to block, you're likely unable to stream content. To check, simply turn off the VPN and try connecting Mubi app again. Most video apps and streaming services attempt to block VPN traffic, so this is the best way to test it. 


10. Give Mubi a Go on a Different Device

Before we go to our most extreme solution, let's see how prevalent the issue is. Attempt to launch Mubi on your computer or any other device connected to your network.

If you're having trouble with Mubi on your TV but it works on all other devices, it's time to reach out to LG support.

If Mubi isn't functioning correctly on any of your devices, it could be an issue with either your own Mubi account or with Mubi's servers.

If you can't find any information on, it is prudent to reach out to Mubi support at for the most recent information.


12. Perform Factory Reset on Your LG TV

We have exhausted all the easy solutions, so now it's time to try a factory reset. This will wipe out all of the TV settings, Mubi app included. Clearing the settings and app data may resolve the streaming app difficulties.

To do this:

  • Press the Settings button on your remote.
  • Access All Settings.
  • Open the General tab.
  • Pick Reset to Initial Settings.
