GPS/UTC time offset not known on Fightfeeder info page

Hi today morning I’ve shifted my antenna (Reason is I’ve mounted that antenna on higher Pipe than the previous one) from it’s original location for few minutes after that again I put that antenna on its original place. Then I power on the device and opened the info page and found that GPS is not running showing ‘GPS/UTC time offset not known’. Any help would be appreciated.

Update- Rebooted from FlightFeeder Control Panel, Problem solved !!
