  • There might be a bug in your router or modem.

How to Fix: McDonald's dcs Error 10021

Restart your Network Connection

As soon as you start getting the error code, the very first thing you should have tried is checking the Internet connection. In many cases, simply restarting the network connection can help.

Check for the App & Device Updates

Many times, if the app or device is not updated to the latest version, then they’ll eventually start creating issues while you are using them.

Therefore, check for the app or device update, and if you find any – then update them right away. For less work, you should switch on the auto-update option from the settings.

Therefore, you should switch devices and try using the McDonald's app on some other device. 

Log out and Log in

Often, you might face a glitch because of your account data in the app. To resolve this problem, all you have to do is log out and log back into your account. For better results, you can try doing the same thing a couple of times.

Re-launch the McDonald's App

In case the device is not the problem, then the McDonald's app is. If it’s about a small bug, then it can be kicked out by simply relaunching the McDonald's app.

To relaunch the McDonald's app, all you have to do is delete the app and install it back from the Google Play Store App Store.
