Model: Deco M9 Plus  
Hardware Version: V2
Firmware Version: 1.9.1

@David-TP 

 

Since I upgraded my M9 Plus to 1.9.1 I have been unable to connect to my Juwel Helialux light via HTTP, getting a error ,essage saying

 

Defended against an attack

Attack from 192.168.x.x

Classification:+SERVER-WEBAPP_login.htm_access(CVE-1999-1533)

 

This worked fine before the upgrade on all previous firmwares, I can connect to the homepage but the issue occurs when I click on a page and it asks me to login with the password.
