"Help sticker" Xshell not connected to Ubantu

At first, my virtual Internet access is via NAT, Xshell can connect ubantu normally.

Later, there was a period of time, the host internet frequently disconnected, so I will network adapter VM1,VM8 disabled.

Another time, trouble company colleague Remote Assistance, virtual machine through the bridge way, connected. However, the next day after shutting down the machine.

OK, here are the questions attached:

　　

SSH is installed and turned on.

　　

The firewall is not started.

　　

　　

The host is able to ping the virtual machine, the virtual machine can also ping the host.

I recently deployed a gitlab on the Ubantu, I will gitlab_url changed to HTTP://192.168.1.109:80, the host is also inaccessible ...

Recently, the problem has been tossing a lot of time, so far unresolved.
