Dear Team,
I am encountering a recurring issue in Power BI Desktop while refreshing data from my SQL Server data source. Below are the details:
Issue Description:
While attempting to apply pending changes or refresh data, I receive the following error message:
OLE DB or ODBC error: [DataSource.Error] Microsoft SQL: A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)
As a result, dependent tables like DATE_TIME_V also fail to load.
Environment Details:
Power BI Desktop version: July 2025
SQL Server data source : Import
Table involved: IVR_SUBHOUR_V
Internet/network connection: using home Wi-Fi to connect to corporate VPN
Occurrence: frequent
Report name: 08-CCC-IVA PERFORMANCE SUMMARY & DETAIL REPORT
Steps Already Taken:
Restarted Power BI Desktop and retried
Request:
Could you please help me identify the root cause and suggest a permanent fix for this transport-level error?

Hi @manoj_0911 ,
You can follow below steps to solve this :
1. Use a Wired Ethernet Connection .
2. Reconnect VPN Fresh before opening Power BI.
3. Split Query: Limit the size of data from IVR_SUBHOUR_V using filters or parameters (e.g., only current month).
4. Check Query Timeout Settings:
Go to Data Source Settings in Power BI.
Click Change Source > Advanced options, and increase Command Timeout to 10+ minutes.
5. Client-Side Configuration
Power BI Desktop Options:
Go to File → Options and settings → Options → Data Load. Under Global → Data Load, increase Background Data Timeout to higher value.
