    Posting this again here. I realized I posted this in the wrong section earlier.
    Working on google cloud instance, ubuntu 16.x.x
    Successfully loaded ispconfig.
    Trying to add first site.
    In ISPconfig: I made a database user, database, ftp and added site.
    I created DNS on google cloud instance.
    I pointed the NS to the google cloud DNS in GoDaddy and it has propagated for over 24 hours.
    I doublechecked passwords. I also changed the passwords to be sure. Still doesn't work.

    PROBLEM: When I type in the domain in the URL, I get ERR_NAME_NOT_RESOLVED
    I've tried to connect with FTP and SFTP and I get Can’t establish connection

    What can I try next?
    Note: this is my first time working with linux. I'm a beginner.

    In Ubuntu use command "whois yourhostname.tld" to see what name servers are used to look up information for that domain.
    In Ubuntu use command host to see what information about your domain those name servers have. In Windows the corresponding command is nslookup. Like so:
    Code:
    host yourdomain.tld ns1.thenameserver.tld

    moved my answer over here:
    There's too much involved as you could hope for a simple answer.

    your domains nameserver need to be correct
    the nameserver should have the correct A or AAAA records to let you browse the destination
    your google cloud server needs to be configured properly since as I remember getting a route to the outside world is not very beginner-friendly.

    and we'd need more information to help I guess, you're going on the internet with the domain, no need to obfuscate it, maybe we can check what is wrong from here.

    Thanks for responding. I had to install whois and it worked to that point. I was able to see the correct name servers (I think)
    I'm now looking up the second part as it told me there was no command "host".

    Sure: I presently own 24 domain names and do shared hosting. I want to move everything over to google cloud or to amazon servers and manage everything myself. Obviously, that is a big order, but I'm going struggle through anyways.
    I'm working with a domain name I don't care about: coffeebreakkitchen.com
    I created a Virtual Instance on Google Cloud using the following. Also, here are my IP addresses. Don't worry, I'm not giving up sensitive info. I'm going to recreate everything once I figure this entire process out.

    ISPConfig Version 3.1.12
    Ubuntu 16.04 LTS

    35.185.65.227
    10.142.0.3

    Duh. I used a capital H. Got it now: Here is what I got:

    Using domain server:
    Name: ns-cloud-a1.googledomains.com
    Address: 216.239.32.106#53

    I don't recognize that address though.

    I did this: apt-get install bind9-host

    Also, I looked up bind9-host and started playing with some of the commands.
    I used the dig command and I don't recognize those IP addresses either. Here are the results.
    root@ubuntu5000:~# dig coffeebreakkitchen.com; <<>>

    nameservers are ok, no issue with that.
    however google nameservers refuse to answer for your domain, is it this https://cloud.google.com/dns/migrating you're doing / need to do?

    Code:
    gcloud dns managed-zones describe yourdomain.com
    
    should return nameServers for that domain, use these at godaddy
    use
    Code:
    dig A yourdomain.com @ns-cloud-a1.googledomains.com
    
    where you replace the ns-cloud-a1.... with one of the returned nameservers to get A record.

    Ok, so I redid the DNS and updated the godaddy ns numbers. The Advanced feature to export the zone record no longer exists in the godaddy DNS Manager. So, I'm going to try to input the A record and CNAME manually.
    dig A coffeebreakkitchen.com @ns-cloud-c1.googledomains.com I think works now. Not sure.

    it looked better as soon as you changed the nameservers to the correct ones. ns-cloud-c1.googledomains.com...
    https://mxtoolbox.com/domain/ looks fine for a start to me

    Thanks for all your help.
    Here is what solved the problem: I went to godaddy DNS, clicked advance and added the IP address to the IPV4 area with the host name of www and saved. Then waited about 3 hours and it just worked. That is after I make DNS Cloud service and added A and CNAME records in google cloud.

    Thanks for all your help.
