MyFRITZ!App report "Error 503"
MyFRITZ!App does not display the MyFRITZ! home page of your FRITZ!Box. When MyFRITZ!App attempts to log in to the FRITZ!Box, it displays the error message "Error 503".
1 Waiting until the automatic lockout period has expired
If the error message is only displayed occasionally and MyFRITZ!App can to log in to the FRITZ!Box without any problems a short time later, then the automatic lockout function was enabled when the error occurred.
The lockout function protects your FRITZ!Box from brute-force attacks. If you are subject to one of these attacks, countless attempts to log on with arbitrary character combinations are made in order to determine and bypass short passwords.
Note:As soon as an attempt to login to the FRITZ!Box (for example when opening the user interface) fails because the wrong login data was entered, the lockout function prevents you from re-attempting to log in for two seconds at first. Each time an attempt to log on fails, the lockout delay is automatically doubled. After seven failed attempts, the maximum of 128 seconds is reached.
- Wait several minutes and then try to log in to the FRITZ!Box with MyFRITZ!App.
2 Reconfiguring the connection to the FRITZ!Box in MyFRITZ!App
If the error message is displayed after each attempt to log in to the FRITZ!Box, then the login data entered for the FRITZ!Box user in MyFRITZ!App is incorrect, or the user was not assigned the right to "View/listen to voice messages, faxes, FRITZ!App Fon and call list" from the FRITZ!Box from the internet.
