In Android lte network, connection fails.

My testing environment.

mcu: 4.2

iPhone: Success

Android: Fail

 

It works well on wifi networks in Android. However, the connection fails in the lte network.

(I think it's an ipv6 problem.)

Below is the Android log.

The test phone is Android and can not be connected only in sk telecom lte environment of Korea. It works fine in the lte environment of the other carriers kt and lg. Also, sk lte works well in iOS environment. If you need more than the attached log, please ask.
