I have mail in a box as a droplet image which I use to host my email and my website. it was working perfectly for over two months. I get the mail of the system check and I dicovered that the DNS server is not resolving my domain name. After some debugging, I have discovered that the issue is related to the DNSSEC, but I can not figure out the problem here.
So when I try to use
dig on my domain name from my image the domain resolution failed. I have executed
root@box:~# /etc/init.d/bind9 status and I got this response
broken trust chain resolving and
bad cache hit.
I have re-updated the DNSSEC entry inside my domain hosting website. I was able to ping my domain name from my droplet for only five minutes and then I got the same error as before.
Do you have any idea how to resolve this issue? Or what is causing it? Do I need to clean the cache? if yes How to do that?
