Unable to access the administrator gateway login for xfinity modem.

So to access the xfinity gateway administrator login page you need to go into a browser type in 10.x.x.1 (x can be replaced with whatever number was set as the ip) and normally a login screen to the modems admin settings SHOULD appear. For thr past week, however, i have been unable to access the login page. It just times out. I have tried resetting the modem using the pinhole through the back, unplugging it or by app. Didn't work. So I tried accessing the adimin login via a different browser. Didn't work.  Next I tried different devices. Tried different computers, tried the phone. Still no response.

And the administrator login page IS NOT the xfinity xfi login. That is a separate thing in itself. 

I am [Edited: "Language"] out of luck right boe and don't k oe what to do. Rhe pinhole in thr back doesn't do a factory reset and the only way I k oe to factory reset aside fromthat is via the administrator settings. 

Can someone help me?
