Camilla GUI in FusionDSP doesn't work

Hello,
I have a problem with FusionDSP. After selecting Pure CamillaDsp gui as DSP I try to click to “Access To Camilla Gui” button, a new Tab in firefox appear with this adress: http://127.0.0.1:5011/ and the message “Unable to connect”
“Firefox can’t establish a connection to the server at 127.0.0.1:5011”.
How can be solved?

Disable and enable FusionDsp. It is because IP isn’t returned properly.
You can also duplicate the tab in web browser and add :5011. Ex : 192.168.1.10:5011
I close this thread. If you have questions post on the FusionDsp related one.
Thanks
