So my high school got an ETC element board (pretty sure this is only its 3rd year in our theater). We got a wireless router for it and set up the iRFR app on our director's ipad (he's the only one willing to pay for it). It worked throughout all of last year, was great for turning lights on for focus or someone else running a couple cues in a show, etc. Recently it just stopped working, the app recognizes the board, and all the settings are right on the board. The app continues to give me the "connection failed connection refused" error whenever I try to connect, any explanation for this?
