Problem : Sonicwall not accessible from new browsers, page cannot be displayed error after entering username and password.

As new browsers doesn’t support RC4 , you need to do some workaround to access Sonicwall

Workaround : change main.html on the browser to diag.html ( for eg 10.10.10.1/main.html  to 10.10.10.1/diag.html

Search for RC4 ,  and disable the checkbox.  Restart

Now you can access Sonicwall , you can upgrade to latest firmware for permanent solution.
