Google Cloud Platform:

DigitalOcean:

edit 50-cloud-init.yaml
vi /etc/netplan/50-cloud-init.yaml
remove private IP address on eth0 (might be 10.10.something - do not remove your public IP the same one you use to SSH into the server or access it)
netplan apply
reboot

DigitalOcean Example:

    eth0:
        addresses:
        - 12.345.678.9/24                 <---whatever this is leave it alone
        - 10.10.0.7/19                    <---Remove this
        gateway4: 46.101.192.1            <---Do not Touch
        match:                            <---Do not Touch
            macaddress: f6:0b:60:97:61:d5 <---Do not Touch
        nameservers:                      <---Do not Touch
            addresses:                    <---Do not Touch
            - 67.xxx.xx.xx                <---Do not Touch
            - 67.xxx.xx.xx                <---Do not Touch
            search: []                    <---Do not Touch
        set-name: eth0                    <---Do not Touch
    eth1:                                 <---Do not Touch
        addresses:                        <---Do not Touch
