How do I make OpenVPN Connect honour the keepalive setting?
It's a bug with OpenVPN Connect, apparently:


  You are absolutely right -- server-pushed keepalive parameters (ping, ping-restart) are being ignored in 1.1.12 and earlier.
  
  Will be fixed in next release.
  
  Thanks,

By using OpenVPN for Android (alternative), I can connect properly.
