i had problems to reboot the CloudKey.

After reboot i could not reconnect.

tail -f /usr/lib/unifi/logs/server.log

i stopped the services

systemctl stop unifi 

and try repair database

mongod --dbpath /usr/lib/unifi/data/db --repair

get the error 

**************
Error: journal files are present in journal directory, yet starting without journaling enabled.
It is recommended that you start with journaling enabled so that recovery may occur.

then i removed the journal files

cd /usr/lib/unifi/data/db/journal

rm *

after that i start repair the database

mongod --dbpath /usr/lib/unifi/data/db --repair

and start the service

 systemctl start unifi
