The chkservd process attempts to connect to “” in order to validate that this service is functioning. If you blocked connections with iptables or the “Host Access Control” interface in WHM, this failure may be a false positive.

To resolve this issue, either open the firewall to allow connections as the root user to “” or disable checks for this service in WHM’s “Service Manager” interface with the “Configure Monitor Settings” link below.


Did you try doing this? You mention that some kind of firewall is enabled.


yes i have webmin firewall the data center installed but not familier with it. csf was causing nothing but problems.


I’m afraid I’m not familiar with webmin firewall. You’re probably better off asking this question in some community dedicated to webmin, as it’s not really related to Let’s Encrypt.

(Unless someone here happens to know how to add that firewall rule, of course :wink:).
