Comment 2 for bug 1883261

I've been testing with the 4.15 kernel and using the following wiki for guidance of using kdump/ssh:
https://ubuntu.com/server/docs/kernel-crash-dump
I first confirmed I could kdump to local disk. Next, I configured kdump per the wiki to use ssh.

However, everytime I cause a crash, the kexec kernel hangs and seems like it cannot reach the network to write the crash file to. Here is the error I see:
[ 387.778745] kdump-tools[735]: Starting kdump-tools:
[ 387.790249] kdump-tools[763]: Connection closed by 13.77.154.182 port 22
[ 387.794756] kdump-tools[744]: * Network not reachable; will try 15 more times

I'm not sure if this is due to a config error on my part or because of the test kernel. Is there any information you could provide to confirm my configration is correct? I'll attach my /etc/default/kexec file.
