System

The typical case is an active firewall either on your server or in the provider's network blocking port 53 communication. Do you have anything like that going on?

Has it ever worked for you and just suddenly stopped working or is this a new installation you have this problem with?

MrFunken commented 5 years ago

First I have tried to move a server to a different location. As it is running on a KVM System, I just copied the system to the new location and changed the IP on the guest system.

But, that did not work and was giving me that error...

So, to make the debugging short, I have tried a clean install. Installed a fresh Debian 9 System, installed mailcow as described in the wiki.

But, I have got the same error O.o

On the network side, there is nothing blocked or firewalled. DNS Requests direct on the system works just fine.

I would say it is an issue with the unbound problem, as I get exactly the same error message as in #585

andryyy commented 5 years ago

Which provider? Some shitty providers block this traffic. Is ufw or firewalld installed and active? It is no mailcow issue, defintly a network issue. :-(

MrFunken commented 5 years ago

We are our own ISP. As I already have mentioned there is no port blocking.

And no, it's definitely not a network issue

It appears you aren't on the latest version of the Unbound image, since you have the /dev/stdout problem, which was fixed recently. Please run ./update.sh in the Mailcow directory and try again.
