NTP error: clock unsynchronized

[hushcoden]

Does anybody have got the same error message? Rebooting the router didn't make any difference.

Code: [Select]

I had some similar NTP clock unsyncd issue some months ago (it was on opnsense version 20.7.5), that got resolved automagically after a couple of days. I still dont know what was the problem, neither others had any clue.

Message: '0x2041', The clock was not synchronized, yet.
Run 'ntptime'
You see: 'status 0x2001 (PLL,NANO)'?
All is fine, the clock is synchronized.

Ah, so it works 

Code: [Select]

getto@hush:~ % ntptime
ntp_gettime() returns code 0 (OK)
  time e3f4e609.555ed070  Thu, Mar 11 2021 18:55:05.333, (.333478690),
  maximum error 500031 us, estimated error 589 us, TAI offset 0
ntp_adjtime() returns code 0 (OK)
  modes 0x0 (),
  offset 2337.078 us, frequency 35.980 ppm, interval 4 s,
  maximum error 500031 us, estimated error 589 us,

Yes, it just looks okay.
First message:

Code: [Select]

PLL         0x0001  /* enable PLL updates (rw) */
UNSYNC      0x0040  /* clock unsynchronized (rw) */
NANO        0x2000  /* resolution (0 = us, 1 = ns) (ro) */

The status returned by ntptime:

Code: [Select]

PLL         0x0001  /* enable PLL updates (rw) */
NANO        0x2000  /* resolution (0 = us, 1 = ns) (ro) */
If your curious where ive got my info from, I'm a nitwit you know

edit: forgot to paste the 'NANO' in 'first message
