Dear Team,
I am not able to access the Hyperion URL outside the server.
But I am able to access the Hyperion url only on the server with only Internet Explorer. If I use Firefox version (41 which doesn't need of remote XUL manager) still it's not opening and it says remote XUL is not configured on firefox. As I remember remote XUL manager not supporting 35 or higher version of Firefox browser. Please find attached below screenshot for the same.

And whenever I trying to open outside the server still I am not able to open the URL. In firefox its appearing same as above. But in the same firefox, I am able to access another Hyperion instance URL. Even in Internet Explorer, I am not able to open Hyperion URL. Please find attached below pic of internet explorer (Outside the server).

But I am able to access different instance url in the same version of firefox outside the server.

Hyperion Version: 11.1.2.3
Thanks in advance.
