Spiceworks won't scan. "No devices ready for network health check yet"?

[Number6]

I have recently installed spiceworks to test it out to see if it's worth rolling out on a production basis.

 

Installation is OK, at least no errors were generated.

 

I initiated a network scan a week or so ago and it seemed to start OK, a few devices and people were detected and inventoried. It picked up some warranty information, etc, etc.

 

I left it running on the Friday and it then transpired that I was off work the next week.

 

When I returned yesterday I saw that no further information had been logged and the scan page is reporting:

 

# 08:13:11 no devices ready for network health check yet. Canceling... (98%)

# 08:13:00 spawning network health check (0%)

# 08:03:50 expanding network list item: 192.168.1.1-254 (254 addresses 192.168.1.1 to 192.168.1.254) (3%)

# 08:03:40 initializing network search (1%)

# 08:03:29 spawning Scan Now (0%)

 

And simply keeps repeating this over and over, it's been running overnight with no change.

 

I can't see anything wrong with the settings and the system was obviously working in some fashion when I originally set it up because it has inventoried a certain amount of data.

 

Has anyone else seen this problem?

 

Any tips for resolving it?
