WINDEV- SQL query timeout

Hi,
We have application developed in WINDEV. We have used SQL server. For one procedure we are getting following error:
---------------------------
Adage - VTest - mode DEBUG - base ADAGE_PROD
---------------------------
StatElt - Echec requête Req_Stat_CompDsDossier
OLE DB access error.
Error Number = 170129

Failure opening file.
System Error Details: Description = Query timeout expired
Source = Microsoft OLE DB Provider for SQL Server
SQL State = HYT00
Error Number = -2147217871

Does anyone know why it's happening? How to resolve this?
