Ios Gdx.net.sendHttpRequest() not active

It error when i use:
moe {
proguardLevel ‘all’
}

and in proguard file:
-keep class com.badlogic.** { ; }
-keep enum com.badlogic.
* { *; }
-keep interface apple.uikit.protocol.UIApplicationDelegate { *; }

when i remove
moe {
proguardLevel ‘all’
}
it show again. But if remove proguardLevel ‘all’ size is too large. How to config proguard in this case, Please?
