MyFRITZ!App reports "FRITZ!Box cannot be reached"

MyFRITZ!App does not display the MyFRITZ! home page of the FRITZ!Box. When it attempts to log onto the FRITZ!Box, MyFRITZ!App displays the error message "FRITZ!Box cannot be reached! Make sure that you are connected with the internet".


  • The FRITZ!Box is either not connected to the internet, did not obtain a public IP address, or it is not correctly configured.

Simply proceed as described below. After each measure, check whether the problem persists.

1 Public IP address required for access

You can only access the FRITZ!Box over the internet if the FRITZ!Box obtains a public IPv4 address from your internet service provider when it connects to the internet.

Access over the internet is not possible if the FRITZ!Box obtains a private IPv4 address.

You can find out whether the FRITZ!Box obtained a public or private IPv4 address by following the steps in our guide Identifying the address range of the IPv4 address for the internet connection.
