Shoot, that's what I have and still doesn't work. When I look at the BI log, it shows the server connected to the IP for my hub, so it's receiving the connection, it just won't change the profile. When I type the whole path out in chrome (http://ip:port//admin?profile=2....) it takes me to the log in page but I still have to log in. Once I do, it just goes to admin?profile=2 in the address bar and nothing loads and nothing changes in BI. I'm not smart at all on GET or other HTTP stuff other than some simple hacks on smartthings code, so I'm probably saying some of this wrong.
Two more thoughts for you:
1) are you using stunnel for https? (I am, but it's running only for non-lan connections, and I'm using the normal lan IP and Port. Also, I turned it all off and tried it but still didn't work)
2) Are you using the default BI webserver files or bp2008's UI2 version of them? I changed mine to the latter, so maybe that is the issue.
Just to run this to ground, I'm using BI version 126.96.36.199. I appreciate the help, I'd really like to get this function running locally so I can do some other network config changes.
