I've done that.
The problem being, it's either not honouring that setting or a port used to connect to the server has changed, and is now becoming blocked via a firewall rule.
If I enter the relevant proxy settings as either proxy address or http://proxy address with the relevant port on each, no connection to the server can be made. I've also hard coded my system to use the proxy for applications which cannot have a proxy set, so all traffic flows via the proxy.
The thing I can't decihper is where it's saving the preferences, as I cannot find a file or registry entry where these are maintained. Exiting and reopening the desktop app, has them saved, so they are held somewhere. Being unable to locate where, I can't then check if they have been saved correctly there (I have come across applications that stored it wrongly, and had to be manually edited previously).
