Get time out when accessing nav/ipdevinfo/{device}

Hi!

Upgraded to latest and greatest a couple of days ago. After that everything works, except accessing devices.

I have http://nav/ as my NAV URL root. Trying to access http://nav/ipdevinfo/%7Bdevice%7D gives:

Gateway Timeout

The gateway did not receive a timely response from the upstream server or application.

Can someone please point me in the right direction for where to start to look? I did a double upgrade. Debian and NAV. To get Debian up and running, including going from PostgreSQL 9.4 to PostgreSQL 9.6 I had to make some room on the hard drive. So I did a "cd /var/lib/graphite/whisper/nav/devices/" + "rm -rf *"

Did I mess up here?

BR,

Jo
