Thread:Project:Support desk/Cookies error after Migration

We're encountering the cookie error: "Montreal Dictionary Wiki uses cookies to log in users. You have cookies disabled. Please enable them and try again." after migrating our site. This error didn't occur on staging. We've edited our localSettings.php to reference the new site. The sessions folder is writable. Our setup is an IP that feeds into a Squid node that feeds to other nodes.

We've been searching for a few days now: any ideas on what to look for? Any help would be appreciated.
