What happens when you encounter a connection problem?
If your game displays a error message (e.g. Could not connect to backend server, Lost connection to Kane's Wrath Online, Could not establish a connection to online services, etc. etc,) when you try to log in or sometimes will just trying to access the multiplayer option are you most likely encountering a connection issue (in rare cases there is a different issue however that is isolated to RA3) that means that your game/system is unable to establish a connection to our game servers this can have multiple causes which im going to collect here together with solutions.
