Tablet App Suddenly Stopped Working - Only Shows Page Cannot Be Displayed

It's possible you're getting an error on your tablet screen when trying to load the TapMango Application. 

It's very likely this is due to the tablet's internet connection being interrupted. There's a few things that could cause this to happen and we're going to go through them step by step.

This article is for if you're having a sudden interruption of service. If you're having difficult connecting the tablet all please see our article on connection issues.

This is different than a solid white screen - and you should be seeing a distinct error message instead

If you're experiencing general issues with your internet and not just the TapMango tablet we strongly recommend you reach out to your Network Administrator or Internet Service Provider first to ensure there isn't a general problem with your store's internet.

Step 1: The tablet may not have finished connecting to your Wi-Fi before 

You may be able to just reload the tablet.

1. Tap the right side of the screen quickly 3 times
2. A menu should appear, select reload
3. If the tablet is connected to Wi-Fi properly the app should reload and load properly. 
4. If not, continue to step 2

 Step 2: Check if Wi-Fi is connected

Wi-Fi may not have connected at all. This is simple to check - you'll need to exit the TapMango applicaiton.

1. Tap the right side of the screen quickly 3 times
2. A menu should appear, select quit
3. The password to quit is 999999
4. Once the app exits look in the top right corner - do you see a Wi-Fi symbol and does it look connected? 
5. If not - see step 3 to check the status of the Wi-Fi connection
6. If so - see step 4 to check if the tablet is able to load anything

Step 3: Check the internet connection's settings

Let's double check it's connected properly.

1. Swipe down from the top left corner of the screen
2. Select the (settings) gear icon to open the main settings - note: your tablet's may look slightly different than the icon displayed here.
3. Select Wi-Fi Settings under Wireless & Networks
4. Does your Wi-Fi show on the list? 
5. If so - does it show 'connected' underneath?
6. If so - continue to step 4 to confirm the connection is active
7. If not - does it say 'Connected, no internet'?
8. If so - see step 5 about power cycling
9. If not - does it say 'Authentication Problem'?
10. If so - the password entered is wrong, press and hold the connection, choose 'modify' and enter the password again. You can scroll and select the box 'Show password' to confirm you're typing in the correct password
11. If not - does it say 'Saved, Secured WPA/PSK'?
12. If so - then tap the connection and choose 'connect' 
13. If nothing happens then press and hold the connection again and choose 'forget'
14. Wait a few seconds for your Wi-Fi to appear again and select it and re-enter the password
15. If you still get the same 'Saved, Secured WPA/PSK' move to step 5 about power cycling

 Step 4: Check if the internet works outside TapMango

To help diagnose the problem we need to see if this is a problem connecting to TapMango or a 

1. Go to the tablet's home screen by pressing the button on the bottom middle of the screen along the black bar. Depending on your tablet this will either be a circle or an icon shaped like a house
2. While on the home screen, select the icon with 6 dots to bring up all the tablet's applications
3. Select (chrome) - this is a web browser
4. It's possible you've never launched chrome before and may need to dismiss some prompts
5. If asked to sign into a google account choose 'No Thanks'
6. If asked to take a tour keep hitting 'next' to skip through the menus
7. If asked to update dismiss the prompt
8. When you're able to see the address bar - select it to type in a website
9. Try google.com
10. If this loads try searching for something and going to a result
11. Does this load okay?
12. If not it's a connection issue - see step 5 about power cycling
13. If yes, you can try and opening the  TapMango application again

 Step 5: Time to reset! Power Cycling!

Sometimes we can't work through the problem by tinkering with settings. The age old turn it off and turn it on could be the solution! This is called power cycling. There's two parts to this the tablet and your modem/router.

Tablet

The tablet is quicker to handle, so let's try it first.

1. Press and hold the power button 2 seconds, or until you see a small pop up appear.
2. Select 'power off' and confirm (note: you may also have a 'restart' option - if so choose that and you can skip the next step)
3. Once the tablet turns off wait 5 seconds, then hold the power button until the screen comes on and shows the tablet manufacture logo.
4. Everything should come back on as normal - once on wait for the wifi to connect
5. You can confirm this with the steps in Step 3 or wait until you see the icon no the top lit up
6. Attempt to load the  TapMango application again -if things load, great. If not move to the next part.

Modem and/or Router

This part takes slightly longer - and depending on how your business is setup you may need to wait until it's a slower time of day. Doing this step will temporarily stop your store's internet connection. When all else fails this is usually the fix.

1. Go to where your store's modem and router is located
2. If you have a single unit - for both the modem and router you'll need to unplug it.
3. If you have two separate units - both a stand alone modem and router - unplug both
4. Wait for at least 10 seconds then plug the equipment back in
5. This process will take 30-60 seconds. Your internet will slow come back on
6. Once you're able to verify it's on again (check another device's connection like Wi-Fi on your phone
7. Now double check the TapMango Tablet has connected again and try launching the  TapMango application again - if things load, great. If not, see below.
