Your server and default gateway need to be on the same subnet

When you set your netmask to 255.255.255.0 you are telling the interface it can only broadcast to other addresses on 139.59.148.x. Anything else needs to go through your gateway, but your gateway is on 138.59.144.1

As the saying goes, "you can't get there from here."

Either the gateway address is incorrect, or you need to change your ip address or netmask. Right now your local device can't broadcast to the default gateway.

EDIT: Just a theory, but could the default gateway possibly contain an error? Should it have been 139.59.x.x? If so, and your subnet was set to 255.255.249.0 you could broadcast to the default gateway at that point.

Either the gateway address is incorrect, or you need to change your ip address or netmask. Right now your local device can't broadcast to the default gateway because they are not on the same subnet.

The IP of your gateway and subnet mask are in conflict.

When you set your netmask to 255.255.255.0 you are telling the interface it can only talk to other addresses on 139.59.148.x but your gateway is on 138.59.144.1

As the saying goes, "you can't get there from here."

Either the gateway address is incorrect, or you need to adjust your netmask.
