Dreamweaver proxy issues

Application: DreamWeaver 18 (build 10136)

OS: Mac OSX 10.11.6

In our network environment we have an authenticated proxy server for all internet facing traffic, which doesn't pose a problem with any AdobeCC apps with the exception of Dreamweaver. Shortly after launching the DW application we noticed persistent dialog boxes requesting proxy authentication. Upon checking our proxy logs we see that it's trying to go to a "local" site (specifically: http://127.0.0.1:58896/socket.io/socket.io.js) so instead of rendering any sites locally it is trying to go via our proxy.

When the system proxy is disabled this is not a problem, so I tried adding 127.0.0.1 as a system proxy exception however the problem remained.

It appears then that DW for Mac does not honor the proxy exceptions defined in the system configuration.

Does anyone know of a workaround for this? Perhaps some location within the DW app that network proxy settings can be changed?

Thanks
