I ran into the same thing trying to install to the Lume Pad. I should add that I tried the solutions above. The device is connecting just fine but I get the same error when it goes to start the server:
D:\UE5-build\Android_Multi>.\win-x64\UnrealAndroidFileTool.exe -p com.YourCompany.MyProject19 -k 98364449477BFF0D1CB586A788C47DA0 push main.1.com.YourCompany.MyProject19.obb “^mainobb”
Trying to start file server com.YourCompany.MyProject19
Did not find a bind listener
ERROR: Unable to connect to 2FF001000001287
D:\UE5-build\Android_Multi>if “1” NEQ “0” goto Error
There was an error installing the game or the obb file. Look above for more info.
