Workarounds for UE-19345: Binding the address from FSocketSubsystemIOS::GetLocalHostAddr fails on arm64 but works on armv7?

I have been running into problems getting a working arm64 build of my multiplayer game running on iOS. When I attempt to connect to a dedicated server using the open console command, the armv7 builds connect fine, but the arm64 builds fail to bind to the FSocketSubsystemIOS::GetLocalHostAddr.

After a few days of hair pulling, and frantic Googling, I eventually found UE-19345, which seems to have been an issue since 4.7. Since the App Store now requires an arm64 build, I can’t be the only person developing a multiplayer game on iOS to have encountered this.

Are there any known workarounds for this problem? Is it only triggered by a specific configuration?
