Common 4You personal mixing app errors & problems
What techs run into most, and what's usually behind it. The step-by-step fix for your exact software is in Ask Roadie.
- Step-by-step fixGet the fix →
4You says up to 40 musicians but connections drop or get refused well before that
Likely cause: Each app is a TCP client of the MixRack; the limit is on TCP sessions, and Wi-Fi airtime saturates long before the TCP limit.

4You shows the connecting screen every time I unlock my phone
Likely cause: iOS suspends background apps and their sockets; the app must re-establish its TCP session to the mixer on wake.

4You won't connect after the app updated on the musician's phone
Likely cause: Allen & Heath apps and mixer firmware share a protocol version keyed on major.minor; a mismatched pair refuses the connection.
- Step-by-step fixGet the fix →
4You won't install or open on an older phone/iPad
Likely cause: Older 32-bit OS builds can't run 64-bit app binaries, and the app/firmware version-lock means you can't mix an old app with new firmware.

4You works at soundcheck but drops out once the audience is in
Likely cause: Hundreds of audience phones and bodies absorb and congest 2.4/5 GHz airtime; soundcheck conditions don't reveal it.

dLive4You / Avantis4You can't find the mixer on Wi-Fi
Likely cause: The app discovers/connects only within the same subnet; with the console on a static 192.168.1.x address, phones must be handed addresses in that range that don't collide with it.
- Step-by-step fixGet the fix →
SQ4You / CQ4You shows no mixer found
Likely cause: The 4You app only sees consoles on its own subnet; a console that never received a DHCP lease (or sits behind the WAN port) is invisible to it.
- Step-by-step fixGet the fix →
updated SQ to 1.6 and now some 4You phones can't connect
Likely cause: Same major.minor version-lock as above, in the other direction.
