Won't stay connected.

[Mark Loukko]

I'm using OpenConnect 1.3 on Windows 10. 

Here is my issue: 
I connect without any issues. Everything works for a minute or less then I
can't access any IPs.

To test:
1. I connect.
2. I start to continually ping a server.
3. Ranging from 30 second to 2 minutes the ping starts to fail.
4. The connection is still active.

Here is an example:

Reply from 142.71.43.42: bytes=32 time=16ms TTL=62
Request timed out.

Any idea why is happening? No warning or errors show up in the log.
