Install patch frozen with MobilePatchingLibrary

Hi, My project has a single chunk which is the default chunk0. I used Game Launcher to generate patch for chunk0. I alse configed"Http Chunk Install Settings" to generate http chunk datas. Then I deployed these datas to server and used MobilePatchingLibrary Blueprint Nodes to install patch. While it was frozen when I launched the game to update patch. It has a bad downloading speed and installing progress, it event needs cost 30 minutes to finish install. I’m sure it has a good network connection. I also tried with two mobile phones, but the results are same. So I don’t know if it’s MobilePatchingLibrary’s issue or something else.Thanks for help!
