Error 10-3 Sling – 7 Fixing Methods

1. Check The Internet Connection

If you are facing the Sling Error 10-3, it might be caused by an internet malfunction or problem in your connection.

The first thing you should do is close the app and restart your router.

If that doesn’t work, then do the following:

1. Go to your TV’s network settings;
2. Check which network you are connected to;
3. If you are connected to the router’s 2.4GHz, it is time to switch to the 5GHz.

Reset The Network

However, if you are already connected to the correct network, you might want to delete the data on your TV. 

1. Go to your TV’s network settings;
2. Locate the Wi-Fi networks connected;
3. Delete the data regarding the current Wi-Fi;
4. Restart both the router and the TV;
5. Connect to the Wi-Fi again.

2. Manage The App

The Sling TV error code 10-3 might also have to do with some problem in the app itself.

For example, the app is not updated, it is corrupted, or there is some problem with its cache. So let’s check how you can solve any problem related to it.

Update The App

First, let’s assume that the app is outdated.

Supposing that your TV allows you to update the app from the main screen, do this:

1. Locate the Sling TV app;
2. Select the app’s options;
3. Choose “check for updates”;
4. If available, install the updates.

If your TV can only update apps through the app store, do this:

1. Open the TV’s app store;
2. Locate the Sling TV app;
3. Choose to update the app if available.

Clear The Cache

Clearing the app cache is a feature offered by some TV models.

Here is how you locate it if it is available:

1. Find the apps on your TV;
2. Access the Sling TV’s options;
3. Locate anything similar to “clear cache,” “erase data,” or “manage data”;
4. Choose to clear or erase the cache/data.

That will eliminate some data that might require you to log into your Sling account again. However, it should correct the error.

Reinstall The App

If your TV doesn’t have the option to clear a single app’s cache, you will need to try and reinstall the app. That will get rid of potentially corrupted files.

Here is how:

1. Locate the Sling TV app;
2. Select the app’s options;
3. Select “uninstall/remove app”;
4. Enter the TV’s app store;
5. Locate the Sling TV app;
6. Install it again.

3. Clear The TV’s Cache

Sometimes your TV can’t clear only one app’s cache. Instead, you need to clear the cache for all applications.

Fortunately, clearing the cache isn’t harmful; much the opposite. Let’s check how you can clear the cache on the most popular TV systems.

How To Clear Roku’s Cache

Roku owners can do this:

1. Click the Home button on the TV remote;
2. Move the cursor to the “Home” option on the TV;
3. Click the “Home” button five times in a row;
4. Click the “Up” button;
5. Click “Rewind” twice;
6. Click “Fast forward” twice.

How To Clear Hisense’s Cache

Here is how you can clear the cache in most Hisense TVs:

1. Press the Menu button on the remote;
2. Navigate to the Settings;
3. Choose “System”;
4. Open the “Application Settings”;
5. Find the “Clear Cache” option and select it.

How To Clear Cache In Other TVs

We know that there are a lot of TVs on the market, and many of them have proprietary systems.

However, it is possible to clear the cache on most of them by paying attention to this:

1. Go to the TV’s settings;
2. Locate “storage,” “system,” “data management,” or anything similar;
3. Find the data of applications;
4. When you see “cache,” you know you have found the correct place;

Remember that clearing the TV’s cache will not delete the apps. Rather, it will clear some data that has accumulated and is now causing trouble on some apps such as Sling TV.

4. Manage The VPN

Since the problem concerns the connection between the TV and the internet, it is safe to assume that a VPN could be the culprit.

Let’s see the first option you can put to the test:

1. Open the VPN app;
2. Disable it;
3. Restart your router;
4. Try opening Sling TV again.

Disable/Tweak The Router’s VPN

Perhaps the VPN is installed in the network and not in one device.

In that case, you will need to do this:

1. Open your router’s settings;
2. Locate the VPN options;
3. Disable the VPN entirely or only for one device (your TV) if possible.

Perhaps your VPN also allows disabling only one app or address. In that case, you should look up the Sling TV service address and add it as an exception to the VPN.

Tip: Some apps don't work with your VPN because your IP is being masked, and the service needs to know you are accessing from an allowed area. So if possible, ensure your VPN still marks you within the coverage area. 

5. Power Cycle Your TV

A simple solution that can do wonders when you don’t know what else to do is to power cycle your TV.

The purpose of the method is refreshing both the hardware and software, thus reestablishing some of the most basic functions of your device.

1. Turn the TV off;
2. Unplug it from the power;
3. Press the power button for up to 15 seconds;
4. Wait one more minute;
5. Turn the TV back on.

Some brands recommend doing the above up to three times. 

6. Sign Out And Back In

If the error 10-3 only happens when you try to watch on-demand videos or live channels, you can navigate the app.

If so, you can easily find your profile page and choose to log out of it.

If you are new to the Sling TV platform, here is how:

1. Open the app;
2. Find “Settings”;
3. Choose “Sign out”;
4. Close the app;
5. Restart your TV;
6. Open the app;
7. Log in again.

Note: We have added a few steps more to the process so it becomes more effective. You could also couple it with the power cycling method.

7. Check The Account Details

Even though the 10-3 error is generally associated with connection issues, it could also stem from account problems.

For example, suppose that you have forgotten to pay for the service.

In that case, your account is active, but you must pay before watching any content. 

• Go to your email app and check if there is a notification from Sling TV regarding your account;
• Open your Sling TV account on a browser and ensure that the payment method is correct;
• Ensure you are trying to access channels you have paid for and available in your living area.

If you still don’t understand what is happening, here is a safe bet: the Sling TV servers are having trouble.

Since the service provides too many channels, some might be unavailable. Thus, try accessing a different one.

Quick Recap

The Error 10-3 Sling generally means there has been a problem connecting your TV to the content you want to watch.

The issue could stem from your TV, router, ISP, or even some account details you have forgotten to update. But now you know how to solve it!
