GeoSCADA Expert Mobile application unknown error during connection

[Antonio_Sgalla]

Good morning, I installed and licensed successfully the GeoSCADA Expert Mobile Server, but when I try to access it from my mobile app I get "Unknown Error" as in the following screeshot.

My device is authorized in the Mobile Server Configurator and when I read the IIS logs I can see it returns the "404 not found" error code.

Could you help me with my problem, please?

Hi Antonio,

you may need help from the Support team here.

You are correct to check the IIS logs. An initial connection from a mobile device will look like:

2025-07-29 10:11:53 192.168.1.29 GET /mobile/service.svc/v1/admin/device/pin - 443 - <address> Dalvik/2.1.0+(Linux;+U;+Android+12;+SM-M315F+Build/SP1A.210812.016) - 200 0 0 126
2025-07-29 10:11:53 192.168.1.29 GET /mobile/service.svc/v1/admin/servers - 443 - <address> Dalvik/2.1.0+(Linux;+U;+Android+12;+SM-M315F+Build/SP1A.210812.016) - 200 0 0 13
2025-07-29 10:11:55 192.168.1.29 GET /mobile/service.svc/v1/LOCAL/token - 443 - <address> Dalvik/2.1.0+(Linux;+U;+Android+12;+SM-M315F+Build/SP1A.210812.016) - 200 0 0 507

You can use a web browser to check the web connection by using the URL:

https://<address/name>/mobile/service.svc/v1/admin/pin

This will return True.

Check that the MOBILECOMPANION service is running, and (in IIS config) that the web server attached to the port is 'ClearSCADAMobile'.
