Hi! Im using mega-20210503 and try to activate a NTP server for the system. Ive a local NTP server, but when is configured in the webgui the result is
NTP : NTP host xxxxxx.com (192.168.0.239) queried
NTP : NTP host (192.168.0.239) unsynchronized
Using a NTP query tool, the server seems to work properly.
If i leave blank the NTP field the result is these:
NTP : NTP host 2.pool.ntp.org (52.6.191.28) queried
NTP : No reply
NTP : NTP host 0.pool.ntp.org (162.159.200.123) queried
NTP : No reply
NTP : NTP host 1.pool.ntp.org (162.159.200.1) queried
NTP : No reply
NTP : NTP host 0.pool.ntp.org (162.159.200.123) queried
NTP : No reply
Im missing somethin?
Thanks in advance!

Does your network configuration have a gateway and proper subnetmask set?
Are you using DHCP or static IP?
Is the local NTP server defined via IP or domainname (e.g. router.local)

Is the local NTP server defined via IP or domainname (e.g. router.local) its a domain name resolved locally.
Its strange when the NTP field is empty, the preconfigured servers dont respond either.

Given the errors when using the pool.ntp.org, the ESP can resolve DNS, but not sure if it can resolve the local DNS.
So for a test you could try to use the local IP of the host running the NTP service.
Your gateway and DNS are set to the same host. I assume it is your router and not some L3 switch that allows to route data to another subnet?
Also check the subnet of the host where the NTP service is running. I assume it is the same subnet?

Yes, are in the same subnet and the GW is the DNS to.
When the NTP is set with the IP address of my NTP, the log show this:
NTP : NTP host 192.168.0.239 (192.168.0.239) queried
NTP : NTP host (192.168.0.239) unsynchronized
What is unsynchronized?, i try setting up the DST -180 (Argentina) to
Thanks!

When looking for "unsynchronized" in the source code, I noticed this link:
https://github.com/letscontrolit/ESPEas ... -586656384
In other words, the "leap indicator" is set to "Reserved" or "Alarm condition" ... well follow the link for a more clear explanation.
No idea why you also get an error on NTP hosts from the pool.ntp.org.
Time zone offset can be set on the Tools->Advanced page.
