Power Apps is a powerful tool that allows users to create custom applications tailored to their business needs. However, like any software, it is not without its challenges. One common error that users encounter is the "Error When Trying to Retrieve Data From the Network." This issue can be frustrating and may impede workflow if not resolved promptly.
Understanding the Problem
The original error message might look something like this:
Error: Unable to connect to the server. Please check your network connection and try again.
This error indicates that Power Apps is experiencing difficulty in establishing a network connection necessary to retrieve data. Several factors could cause this issue, such as network connectivity problems, misconfigured connectors, or data source limitations.
Analyzing the Issue
Common Causes
-
Network Connectivity Issues: The most common reason for this error is that the device running Power Apps is experiencing network issues. This can include Wi-Fi disconnections or issues with your mobile data.
-
Misconfigured Data Sources: If the app is trying to connect to data sources (like SharePoint or SQL Server), any changes to those sources or incorrect configurations can lead to this error.
-
Firewall and Security Restrictions: Organizational firewalls or security settings can block Power Apps from accessing necessary data.
-
Data Source Limitations: Certain data sources have limitations on the number of connections and may deny access if these limits are exceeded.
Steps to Resolve
To effectively troubleshoot the error, follow these steps:
-
Check Your Internet Connection: Ensure that your device has a stable internet connection. You can do this by testing access to other websites or apps.
-
Verify Data Source Connection:
- Navigate to the Power Apps portal and check if your data connections are correctly configured.
- Confirm the connection settings for any external data sources, ensuring credentials are accurate.
-
Review Firewall Settings: If you're in an organization, reach out to your IT department to confirm that Power Apps is whitelisted in your firewall and security settings.
-
Test Data Source Availability: Try accessing the data source outside of Power Apps (like logging into SharePoint directly) to ensure it's online and functioning properly.
-
Consult Power Apps Documentation: The Microsoft Power Apps documentation can provide detailed troubleshooting steps and solutions for various issues.
Practical Example

One day, users start to report the error message while trying to access the app. Upon checking, you find that your company’s internet connection had been unstable due to maintenance work. Fixing the connection resolved the issue, and users were able to access the data seamlessly again.
