Lansweeper assets not being Scanned

[jordan_alber]

I cannot figure out why some of our assets are not being scanned. They have been initially scanned before. Here is the lsagentlog.txt :

Jordan,

I don't know if your problem is the same as ours, but when I contacted support they stated that there has been "a large increase in the volume of assets passing through the LsAgent relay, which has led to some intermittent connection issues."

Support also provided the following information.

The Lansweeper service will connect to the relay in the following intervals:

• Every 5 minutes to synchronize configuration (asset groups, schedules, etc.)
  
• Every 60 minutes to retrieve scanned assets. All assets that are awaiting retrieval on the relay are picked up during each interval.

These connections have a timeout of 5 minutes.

I use the following report to show when my assets were last scanned using LsAgent.

Select Top 1000000 tblAssets.AssetID,
  tblAssets.AssetName,
  tblAssets.Domain,
  tblAssets.Username,
  tblAssets.Userdomain,
  Coalesce(tsysOS.Image, tsysAssetTypes.AssetTypeIcon10) As icon,
  tblAssets.IPAddress,
  tsysIPLocations.IPLocation,
  tblAssetCustom.Manufacturer,
  tblAssetCustom.Model,
  tsysOS.OSname As OS,
  tblAssets.SP,
  tblAssets.LsAgentVersion,
  tblAssets.LastLsAgent,
  tblAssets.Lastseen,
  tblAssets.Lasttried
From tblAssets
  Inner Join tblAssetCustom On tblAssets.AssetID = tblAssetCustom.AssetID
  Inner Join tsysAssetTypes On tsysAssetTypes.AssetType = tblAssets.Assettype
  Inner Join tsysIPLocations On tsysIPLocations.LocationID =
    tblAssets.LocationID
  Inner Join tblLsAgentAsset On tblAssets.AssetID = tblLsAgentAsset.AssetID
  Inner Join tblState On tblState.State = tblAssetCustom.State
  Left Join tsysOS On tsysOS.OScode = tblAssets.OScode
Where tblAssets.LsAgentVersion Is Not Null And tblState.Statename = 'Active'
Order By tblAssets.Domain,
  tblAssets.AssetName
