Fix: A Timeout Occurred While Loading The Connections Picker Power Apps

If you’ve ever tried importing a Power Apps solution into a new environment and suddenly hit this error below:

You’re not alone. This error is frustrating, confusing, and honestly… poorly explained by Microsoft.

I personally faced this issue while importing a solution into a new Power Platform environment. The import failed. The connections picker didn’t load. And there was no clear error message explaining why.

After searching through community threads and blog posts and testing by trial and error, I found a simple workaround that actually works.

In this article, I’ll explain the best practices to avoid this issue in future solution imports.

A Timeout Occurred While Loading the Connections Picker Power Apps

Let’s understand the error message:

A timeout occurred while loading the connections picker. Widget ID: '0b746b73-0b22-440e-85bc-4f1f-c7a61672'

When we import a solution, Power Apps needs to:

1. Read all the connectors used in the app
2. Load the connection references
3. Ask you to map them to existing connections

This screen is called the Connections Picker. Now the problem is:

In Modern environments, this picker sometimes fails to load completely, especially when:

• The solution has many connectors
• Custom connectors are involved
• Environment permissions are slightly misconfigured
• Backend APIs respond slowly

Instead of handling it gracefully, Power Apps simply times out. No helpful message. No retry button. Just failure.

Why This Happens More in New Environments

This issue shows up more often in new or freshly created environments because:

• Connections are not yet established
• Connection references exist, but are unresolved
• Permissions are still syncing
• The environment UI defaults to the Modern experience

You might notice one or more of these:

• Import starts but fails at “Configure connections.”
• Blank or frozen connections picker
• Infinite loading spinner
• Timeout error with a widget ID
• The same solution works fine in another environment

This is a platform behavior issue, not a mistake in your solution.

[Solved] A Timeout Occurred While Loading the Connections Picker Power Apps

After testing multiple approaches, this is the most reliable fix:

Switch the environment from Modern to Classic, import the solution, then switch back.

Yes, it’s that simple. Let me walk you through it step by step.

1. Open Power Platform Admin Center.
2. Select Manage, select Environments, and then select the environment where the issue occurs.
3. Select Settings.
4. Expand Product, and then select Features.
5. Set the Advanced Settings redirection toggle to Off.
6. Click on Save.

Now that the environment is in Classic mode, as shown in the image below.

1. On the top header, click on Settings.
2. Click on Solutions.
3. Click Import.
4. Upload your solution ZIP file.
5. Proceed to connection mapping.

Once you imported the solutions successfully! You can now switch back to the Modern Experience by turning on the Advanced Settings redirection toggle.

Now open Power Apps Studio. Your solution will load normally as shown in the image below.

Conclusion

I hope you found this article helpful! In this article, you learned why the “A timeout occurred while loading the connections picker” error happens during solution imports.

Instead of rebuilding your solution or troubleshooting connectors, temporarily switching to the Classic experience lets the import complete successfully. If you’re stuck with this error, don’t rebuild your solution. Just remember:

Switch to Classic → Import Solution → Switch back to Modern
