After update the firmware from 5.1.1 to version 5.1.6 I can't login to the EAP225. The connection to the IP via browser is not possible.

On firefox I get the message " PR_END_OF_FILE_ERROR " and on EDGE " ERR_CONNECTION_CLOSED ".

The same errors I get, when I try "http://tplinkeap.net".

The login via Omada Controller works and it shows me the correct IP of the LAN. The EAP225 is running and I can connect to both WIFI (2.4 and 5 GHz).

How can I fix this. Bevor the update it works correctly.
