How to get rid of the Tesla 504 Vehicle Connection Error?

Fix 1: Check your internet connection speed and stability

The internet connection plays a very important part in connecting you to various online servers.

If there is an issue with the internet connection, it will become really difficult for you to reach Tesla servers to access the features of the app. Therefore, it becomes really important for you to check the speed and stability of your internet connection. 

You can do this by fishing out your mobile and Googling Internet Speed Meter. Once you launch the tool, run a test for the internet connection.

Now you will see a report for the current upload and download speed of your connection. If you see that the speed is slow or inconsistent, try to switch to a different network or talk to your internet service provider for further help.

Fix 2: Make sure that the Tesla app on your device is updated

The Tesla app receives regular updates in the form of bug fixes and the addition of new features. For these features to reach your device you need to make sure that you regularly update the app.

Sometimes, users update the update notifications to address the matter later. Usually, they end up forgetting about it, and the” later” never comes. 

When you face the error code make sure that the Tesla app is updated to the latest version. If it is not, install the latest version and then retry. 

In most cases, the issues with the app are resolved through an update.

Fix 3: Update the software on your Tesla vehicle

The Tesla vehicle firmware also needs to be updated so that it can connect to the app and eventually, the Tesla server.

When you receive notifications for the firmware update on Tesla, make sure that you do not delay the process and install the update immediately.

Fix 4: Restart the Vehicle

Sometimes the processes on the vehicle get stuck and this is because of the technical glitches that might be temporary. You need to keep in mind that this is not a solution for the deeper issues on your car.

This can usually be solved easily by restarting the vehicle. This shuts down the firmware on the vehicle and removes the conflicts with the software. 

When you restart the vehicle, hopefully, the issues with the vehicle firmware will be resolved. 

If this still does not help, there might be deeper issues with the vehicle and you need to solve them.

Fix 5: Make sure that you are not trying to connect during Tesla server downtime

The server is also sometimes deliberately taken down due to a prior scheduled maintenance session. 

In this case, you can search for a down detector website and get a real-time report of the Tesla server outage. If your area is facing server downtime, you need to wait for a while till the issue is resolved.

Fix 6: Log out of your Tesla account and then log back in

This can include the error code 504 which will not let you connect to the server. To reinitiate the authentication process, you need to log out of your Tesla account and then log back in after a while.
