So, you’ve turned on your Firestick, and Sling isn’t working.
What’s the problem, and how do you fix it?
I’m about to walk through 12 ways of fixing your Firestick, from the simplest to the most complicated.
By the time you’re done reading, you’ll be watching Sling in no time.
1. Power Cycle Your TV
If Sling isn’t working on your Firestick, there could be a problem with the TV’s software.
Modern smart TVs have built-in computers, and computers sometimes hang.
And if you know anything about computers, you know a reboot solves many problems.
Don’t just use your TV’s power button.
The button will turn off the screen and speakers, but the electronics don’t turn off; they go into standby mode.
Instead, unplug your TV and leave it unplugged for a full minute to drain any residual power.
Plug it back in and see if Sling TV will work.
2. Restart Your Firestick
The next step is to restart your firestick.
There are two ways of doing this:
- First, do the same thing you did with your TV. Unplug your Firestick, leave it unplugged for a minute, and plug it back in.
- Alternatively, scroll right to your Firestick’s “Settings” menu. Select “My Fire TV,” then “Restart.”
3. Check Your Internet Connection
Sling TV is a cloud app, and it won’t work without an internet connection.
If your internet is slow or disconnected, Sling TV won’t load.
The easiest way to test this is to use another app.
Open a streaming app like Prime Video or Spotify and see if it works.
If everything loads and plays smoothly, your internet is fine.
If it doesn’t, you’ll need to do some more troubleshooting.
Unplug your modem and router, and leave them both unplugged for at least 10 seconds.
Plug the modem back in, then plug in the router.
Wait for all the lights to come on and see if your internet is working.
If it’s not, call your ISP to see if there’s an outage.
4. Clear Sling TV App Cache & Data
Like most programs, Sling TV stores data in a local cache.
Normally, the cache speeds up your app by negating the need to download commonly-used files.
However, cached files can get corrupted.
When that happens, you’ll need to clear the cache to get the app to run properly.
Here’s how it’s done:
- Go to the “Settings” menu, then select “Applications.”
- Scroll down to “Manage Installed Applications.”
- Scroll down and select “Sling TV.”
- Click “Force Stop,” then scroll down and select “Clear Cache.”
- If that doesn’t work, repeat the previous steps, but click “Clear Data” after you click “Clear Cache.”
5. Reinstall the Sling TV App
If clearing the cache and data didn’t work, you may need to Reinstall Sling TV altogether.
To do this, follow the first two steps above to get to the “Manage Installed Applications” screen.
Select “Sling TV,” then choose “Uninstall.”
In a few seconds, the app will disappear from your menu.
Go to the app store, search for Sling TV, and reinstall it.
You’ll have to re-enter your login information, but that’s only a minor inconvenience.
6. Install the FireTV Remote App
One interesting method I found was use the FireTV Remote App.
This is a smartphone app that’s designed to pair your phone with your Amazon Firestick.
It’s free on Android and iOS, and it installs in under a minute.
Once you’ve set up the FireTV Remote App, Launch the Sling TV app on your smartphone.
Once you reach the home screen, your Firestick should launch the Sling application automatically.
From there, you can control it using your Firestick’s remote.
7. Disable Your VPN
A VPN can interfere with your Firestick’s internet connection.
For a variety of reasons, Amazon doesn’t like serving data over a VPN connection.
This isn’t only an issue with Sling; a VPN can interfere with any Firestick app.
Turn off your VPN and try launching the Sling streaming app.
If it works, you can add the app as an exception in your VPN.
That way, you can keep your digital protection and still watch your favorite shows.
8. Update Your Firestick Firmware
Your Firestick will automatically update its firmware.
Under normal circumstances, you should be running the latest version.
However, you may be running an out-of-date version.
A new version may even have introduced a bug, and Amazon has already completed a patch.
In these cases, updating your firmware can solve the problem.
To do this, go to your Settings menu, then select “Device & Software.”
Click “About,” then choose “Check for Updates.”
If your firmware is up to date, you’ll see a notification.
If not, your Firestick will prompt you to download the latest version.
Wait a minute for the download to finish, then return to the same “About” page.
Instead of “Check for Updates,” the button will now say “Install Updates.”
Click the button and wait for the installation.
In a minute, you’ll see a confirmation.
9. Is your Firestick 4k Compatible?
If you have a 4K TV and you’re trying to stream Sling in 4K, you need a compatible Firestick.
Some of the older models don’t support 4K.
Any of the current Firestick versions support 4K video right out of the box.
To find out whether yours is compatible, you’ll have to search for the specific model number.
Unfortunately, Amazon doesn’t maintain any kind of table with specs for their models.
The best thing to do is set your TV to 1080p mode.
If your 4K TV allows this, try it and see if your Firestick works.
10. Check if the Sling TV Servers are Down
There might not be anything wrong with your Firestick or your TV.
There might be a problem with the Sling TV servers.
To find out, you can check the official Sling TV Twitter account.
Downdetector also tracks outages on many platforms, including Sling TV.
11. Test on Another TV
If nothing else has worked, try using your Firestick on another TV.
This isn’t a solution, per se.
But it lets you know if the problem lies with your Firestick or your television.
12. Factory Reset Your Firestick
As a last resort, you can perform a factory reset on your Firestick.
This will wipe your apps and settings, so it’s a headache.
But it’s a sure-fire way to fix any software or firmware issues on your Firestick.
Go to your Settings menu and scroll down to “My Fire TV,” then select “Reset to Factory Defaults.”
The process will take five to ten minutes, and your Firestick will restart.
From there, you can reinstall Sling TV and see if it works.
As you can see, getting Sling working on your Firestick is simple.
You might have to spend some time in the menu running updates and checking other settings.
But at the end of the day, none of these 12 fixes are complicated.
With a little patience, you’ll be streaming your favorite shows again soon.
