Did you follow those instructions?
Unable to communicate with 192.168.11.1. Please verify DNS and interface configuration, and that pfSense has functional Internet connectivity.
Isn't 192.168.11.1 your pfsense box? You should be pointing it at your webserver address?
thank for your answer.
I've used the instruction..
192.168.11.1 is local server machine.
package & config are in the local server machine.
Are you missing files in the xmlrpc folder on the www root? The repository was down for a few days so the git clone wouldn't have worked. Try cloning the xmlrpc again.
