Windows client only shows as 'Offline' in user-profile 'Devices' tab

• Problem: Client software has been installed and has contacted the Magnus Box server at least once, registering as a new device in the user-profile Devices tab, but now only shows as 'offline'.
• Causes:
  1. The software is not running, or
  2. The software is not able to communicate with the Magnus Box server

1. The software is not running on the device
   • Check that the software widget is running in the system tray
   • If not running, start the software from the 'Start' menu.
   • If it won't run, consider reinstallation.
   • Check whether the local antivirus program is interfering.
2. The software is not able to communicate with the Magnus Box server
   • Check that the software can communicate: Simulate a login via the following terminal command from the Windows device running the client software, substituting appropriately for 'username', 'password', 'yourURL':

     curl -v -X POST --data-urlencode "Username=<username>" --data-urlencode "AuthType=Password" --data-urlencode "Password=<password>" <yourURL>/api/v1/user/web/session/start
     

     **Note: Requires Windows 1809 onwards, or that you install Curl: https://curl.haxx.se/windows/. For older systems, the following command can be run (replacing the same variables as above):

   Invoke-Webrequest -Uri https://<yourURL>/api/v1/user/web/get-user-profile-and-hash -Method POST -Body @{Username="<username>"; AuthType="Password"; Password="<password>"} -UseBasicParsing

   • A successful output similar to the following will verify that the API is accessible from the device:

     {"SessionKey":"abc1fd20-7177-12362-88ba-863efgfe07b0","SessionType":"user","Status":200,"Message":"Logged in OK."} Connection #0 to host <yourURL> left intact
     		

   • Any failure may point to the cause (eg incorrect password, network issue).
   • Check network connectivity
