I also tried to add my Server but I am facing 2 issues.
First issue:
ntpd seems not answering to IPv6 requests.
See Screenshot:
second issue:
I get error message while adding the Server:
nvalid stratum response from 185.170.216.123 (Your server is in stratum 0). Is your server configured properly? Is public access allowed? If you just restarted your ntpd, then it might still be stabilizing the timesources - try again in 10-20 minutes.
Anyone able to assist?
I checked Firewall Config - should be fine.
i can also provide access to the server if someone wants to check himself/herself.
it looks like your ntpd isn’t synchronized (stratum 16) and isn’t listening on the ipv6 address behind the hostname (either the ipv6 is wrong or ntpd isn’t listening)
What is the output of ?: ntpq -pn ss -lup journalctrl -u ntpd |grep -i listen
(maybe the ntp instead of ntpd - didn’t remember the service name)
Maybe you start a new thread, so you won’t “hijack” this one to debug your problem.
