Hi guys,
I am sure this a matter of “user error”, but I am stuck and need a fresh pair of eyes.
Situation:
I have the LE SSL setup on my server, their verification confirms my domains are accessible. And, I followed these very awesome instructions on your site to prep postfix for mail relay . I can reach my host’s default homepage at https://example.com
Problem 1
My DNS records aren’t being found when I attempt to validate domain, set up SPF and/or Domain Keys/DKIM with mailjet relay host.
So I used Vmin > Logs & Reports > Check Connectivity and it failed with the following error message:
Problem 2
Failed to check connectivity HTTP/1.1 503 Service Unavailable Verify that your DNS server is running, that software.virtualmin.com can be resolved, and that no firewall is blocking outgoing HTTP requests.
So, I checked bind9, systemctl status bind9
and was happily buzzing, along, no errors.
Things I’ve investigated:
1.) I checked FirewallD that said Port 53 and all the other necessary ports were open.
2.) I verified that my vps firewall and Firewalld have identical settings.
3.) From my home computer I ran sudo nmap -p- XX.XXX.XX.XXX
it too verified that the corrects ports are open:
PORT STATE SERVICE
21/tcp open ftp
22/tcp open ssh
53/tcp open domain
80/tcp open http
110/tcp open pop3
143/tcp open imap
443/tcp open https
465/tcp open smtps
587/tcp open submission
993/tcp open imaps
995/tcp open pop3s
2222/tcp open EtherNetIP-1
10000/tcp open snet-sensor-mgmt
20000/tcp open dnp
Nmap done: 1 IP address (1 host up) scanned in 31.25 seconds
So at this point, I’m just plain confused.
Does anybody know what I am missing?
Thx
