My network interface has started to refuse to come up on boot, I can run

sudo dhclient

Once it boots and it will start up and obtain an IP address however I didn't used to have to do that. I checked my Netplan (50-cloud-init.yaml) file and it looks to be configured but when I go to boot the only thing that comes up is the loopback interface. I have also noticed since this started that my network performance is much lower, and sometimes will quit working for a few minutes. But I can't find anything in the syslog to point me to the reason. Any suggestions on where I should start?\

I checked my Netplan config file and it looks right I think:

trever@server:/etc/netplan$ cat 50-cloud-init.yaml 
# This file is generated from information provided by
# the datasource.  Changes to it will not persist across an instance.
# To disable cloud-init's network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
            dhcp4: true
    version: 2
