My server provider blocked NTP port because they said there was an NTP attack. Now I cannot sync date and time in my ubuntu 18.04 server.
How can I sync time?
This is ntpdate -q 0.pool.ntp.org
result:
server 195.50.171.101, stratum 0, offset 0.000000, delay 0.00000
server 176.235.41.255, stratum 0, offset 0.000000, delay 0.00000
server 86.108.190.23, stratum 0, offset 0.000000, delay 0.00000
