Error Message: Warning: Ther router is failed to connect to NTP server, please check your Internet

Hello,

I am having issues with the Date NS RIMW OD my R7000 NightHawk router. Those are showing incorrectly. I need to schedule router downtime. However, since the router time is showing incorrectly the scheduling is getting messed up as the scheduling time (I believe) works based on the router time. I am attaching  a screen shot of the NTP setting where the probem is. I have not yet been able to find a solution yet though I tried to use Google NTP server time. 

I would appreciate any help towards resolution of this issue. Thanks in advance.
