It rarely happens that you are without connection to CleanManager's servers.

If you still experience problems, you can find troubleshooting guidelines in this article.

In this article, you will find answers to issues primarily related to your internet connection.

See how you can solve the connection issue, or alternatively how to start and stop your tasks using an NFC tag without internet connection.

Error search when “no connection to the server”

This issue is often caused by problems with your 3G/4G/5G connection, your SIM-card, or Wi-Fi. Below, you can see how to make sure if your device is connected to the internet. 

	Check your data settings
	You find your data settings here: iPhone: Settings > Mobile Data > Mobile Data (Click on the slider to activate/ deactivate mobile data) Android:  Settings > Connections > Mobile Networks (Click on the slider to activate/ deactivate mobile data)

	Check your Wi-Fi settings
	Unless you connect the phone to your company's or your customer's Wi-Fi, the Wi-Fi should always be deactivated. Otherwise, your phone might connect to a guest network with no connection. You deactivate your Wi-Fi here: iPhone: Settings > Wi-Fi > Wi-Fi (Click on the slider to activate/ deactivate Wi-Fi) Android:  Settings > Wi-Fi > Wi-Fi  (Click on the slider to activate/ deactivate Wi-Fi)

	Do you have a network connection?
	If your data is turned on and your Wi-Fi is turned off, check if your phone has an internet connection. You can check this in your browser Safari/ Chrome by accessing cleanmanager.org. If there is no internet connection, the issue might be with your SIM card, e.g. you ran out of data.

	Mobile data + Wi-Fi turned on
	If you are working in an area with different Wi-Fi signals, your phone will often change in between networks. This causes your app to try to establish a connection every time the phone changes networks. Therefore, turn off your Wi-Fi and only use your mobile data.

Start and end a task without internet connection and how to synchronise tasks

This is how you start and end your task offline with the CleanManager app, and how to synchronise the tasks afterward when you have re-established your internet connection:

There are 3 steps in the process:

Start a task with an NFC tag (offline)

 

End a task with an NFC tag (offline)

 

Task synchronisation in CleanManager (online)

 

NOTE:

The task will not appear in CleanManager's system until the task has been synchronised, i.e. the administrator and supervisors will not be able to see updates for the task until that has been done.

Let's get started:

Start a task with a NFC tag (offline)

	Click on Start task
	Activate NFC scanner by clicking within the circle (Android Smartphones are already ready to scan)
	Scan the NFC tag
	Click on Synchronise later (This will automatically be shown if you are not connected)
	The task has now been started
	You can still attach pictures and comments to your task

End a task with a NFC tag (offline)

  

	Click on End task
	Activate NFC scanner by clicking within the circle (Android Smartphones are already ready to scan)
	Scan the NFC tag
	Click on Synchronise later (This will be shown automatically if you have no internet connection)
	The task is now ended and saved under the section Synchronise old tasks

	Task synchronisation in CleanManager (online)
	You can synchronise your task when your internet connection is re-established.

 

	Click on the button Synchronise old tasks
	Click on the registered task that you want to synchronise
	Choose an existing task that you want to synchronise your task with in CleanManager, or create a new task.
	Click on the button Synchronise
	The task is now synchronised
	When all tasks are synchronised, the button Synchronise old tasks will disappear
