Error Impediment Every domain failed DCV

Hi, I'm new to this forum, and I don't know if I post this in the right category or not. My problem is with the AutoSSL in WHM, some of my domains have a success, and some got error "ERROR Impediment: TOTAL_DCV_FAILURE: Every domain failed DCV" What I realize was when using command: dig +trace, I got BAD (HORIZONTAL) REFERRAL on every domains. I've been googling for days without luck. I want to know what should I do to correct this Here is when I did dig +trace

Hello, What if any firewall are you using? If no 3rd party software what are the iptables rules present? You can get a list of them by running something like: iptables -S

Hi CpanelLauren, Thank you for the reply, I'm using CSF firewall, I've tried disabling the CSF for couple of days, but the error still the same, here is when I disabled the CSF

[root@mars ~]# iptables -S
-P INPUT ACCEPT
-P FORWARD ACCEPT
-P OUTPUT ACCEPT
-N cphulk
-A INPUT -j cphulk

and the dig command still reply BAD HORIZONTAL REFERRAL

This issue is most commonly attributed to a misbehaving firewall rule which is why I suggested checking iptables, do you happen to have a hardware appliance connected to the server? If not or you can rule out it being a cause of the issue, I'd suggest opening a ticket with us to look further into it.

Error Impediment Every domain failed DCV
