In the provided sources output the resolution is in days, so we don't
know how much they agree. If you bring the clock closer, what does it
say for the same servers?

In chrony-3.4 the initstepslew sources are added with the offline
option, so if the sources are responding, but there is no clock update
before the burst ends, it will stop polling and get stuck. You can
unstuck it with "chronyc online".

In chrony-4.0 the offline option was removed from initstepslew sources
and this shouldn't happen anymore. It should make a burst of 4
requests and then give up after another 4 requests at the 64s polling
