At my company, all web traffic has to go out through a proxy. This causes all sorts of issues that we have to figure out when apps are inconsistent about how they detect proxy settings. For Alfred, I haven't been able to figure out what to whitelist for updates. I get notifications that an update is available, but when I go to the settings to actually download it, I see the error "Unable to contact update server". Is there any way to find out what exactly Alfred is using (curl, wget, something else) and/or where it is going so I can whitelist this?
