Speedport Plus Sercom Plus ( Cosmote VDSL ) Login bug

If you are a Cosmote(Greece) user you may experience a blank screen when you try to login to the configuration panel. The issue affects Safari , Safari iOS (and also tested on Chrome for iOS, Chrome for Mac it is working)

The console error displays:

Blocked script execution in ‘http://192.168.1.1/' because the document’s frame is sandboxed and the ‘allow-scripts’ permission is not set.

The easy solution is go directly to http://192.168.1.1/html/login/index.html to login.

This error may occur due to the HTTP/0.9 protocol used by the modem webserver and blocked by Safari version ≥ 10 .

Affected firmware : 09022001.00.030_OTE4
