So, I have changed my server location from US to Lithuania and my server stopped working

I can connect to my db and virtualmin but only with my IP

zone

/etc/bind/named.conf:

include "/etc/bind/named.conf.options";
include "/etc/bind/named.conf.local";
include "/etc/bind/named.conf.default-zones";
key rndc-key {
    algorithm hmac-sha256;
    secret "....";
    };
controls {
    inet 127.0.0.1 port 953 allow { 127.0.0.1; } keys { rndc-key; };
    };

/etc/bind/named.conf.options

options {
    directory "/var/cache/bind";

    // If there is a firewall between you and nameservers you want
    // to talk to, you may need to fix the firewall to allow multiple
    // ports to talk.  See http://www.kb.cert.org/vuls/id/800113

    // If your ISP provided one or more IP addresses for stable 
    // nameservers, you probably want to use them as forwarders.  
    // Uncomment the following block, and insert the addresses replacing 
    // the all-0's placeholder.

    // forwarders {
    //  0.0.0.0;
    // };

    //========================================================================
    // If BIND logs error messages about the root key being expired,
    // you will need to update your keys.  See https://www.isc.org/bind-keys
    //========================================================================

    //dnssec-enable yes;

How do you diagnose that it stopped working?

First of all, the site doesn't open, second of all using a port checker and a DNS checker

Your name servers are:

Nameserver: ns1.goodjobs.ro
Nameserver: ns2.goodjobs.ro

As they are within the same domain, they need glue records at the parent .ro zone, but they are missing:

goodjobs.ro.        86400   IN  NS  ns1.goodjobs.ro.
goodjobs.ro.        86400   IN  NS  ns2.goodjobs.ro.
/usr/bin/dig: couldn't get address for 'ns1.goodjobs.ro': no more

You can set the glue records through your registrar.

Furthermore, you need at least two name servers. The screenshot of your zone shows you are trying to point both ns1 & ns2 to the same IP address. Get a secondary name server or use an external DNS service altogether.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
