I am trying to access J-Web on my SRX, unfortunately when I try to https browse to it (I have tried Chrome and IE) I am unable to connect. For instance on Chrome I get the error ERR_TUNNEL_CONNECTION_FAILED. If I try to http to the device I get "Could Not Connect, Description: Could not connect to the requested server host." I can ping the device and SSH to it from my machine. I have tried restarting it and restarting the web-management service.
Thanks for coming to my aid on this one! It was really just a human blunder....
I was connected to the device with a statically addressed LAN port on a laptop. Meanwhile the laptop was connected to our enterprise network via wireless, so I could remote into my laptop and work on the juniper from my main machine. The device didn't mind responding to ping or allow SSH while I worked in this manner.
When I turned the wireless function off on the laptop and removed the proxy settings the GUI worked fine. Its always the basic things.
