Apache 403 when accessing via IP I'm running a web server on Yosemite but have run into a bit of an issue. I can access web server via localhost, 127.0.0.1 and locally on other computer server.local.

But I can't access it via IP address i.e. 192.168.0.100 or by internet IP I get the following error message

Error code 403.
Message: Not Serving Client 82.15.XX.XXX.
Error code explanation: 403 = Request forbidden -- authorization will not help.
I just want to echo what @Gik said. I was having the same problem but didn't notice the answer because it was a comment. PlexConnect was causing the issue. To resolve, Run the PlexConnect script in Applications/PlexConnect-master/support/OSX uninstall.bash
