Question details

Users encounter a connection refusal message when attempting to view a Microsoft Stream video that has been embedded into a Microsoft Sway presentation.

Product
Microsoft Stream and Microsoft Sway
Device & OS
not provided
Scenario
Embedding and playing organizational videos from Stream inside a Sway digital presentation.
Observed behavior
The embedded video iframe fails to load the content, instead displaying an error message stating that the connection was refused.
Before you start

Verify that you are actively logged into your Microsoft 365 enterprise or school account on your current browser, as authentication issues are a primary cause for embedded videos failing to load.

Solution 1Recommended

Verify Direct Video Access and Viewer Permissions

Ensure the video functions normally on its own and that the intended audience actually has the necessary permissions to view it in Microsoft Stream.

Embedded Microsoft Stream videos respect the original permission settings of the video. If the viewer is not granted access, or if the video is restricted to specific users, the embed will refuse to connect in Sway.

1
Open the video directly

Navigate directly to the Microsoft Stream URL of the video in your web browser to confirm that the video itself is available and playing correctly.

2
Check video permissions

In Microsoft Stream, click on the video's 'Update video details' (pencil icon) and review the 'Permissions' section. Ensure that 'Allow everyone in your company to view this video' is checked, or that specific viewers are explicitly added to the list.

3
Re-embed the link

Copy the updated embed code or share link from Stream and paste it back into your Sway presentation's embed card.

Permission Confirmed: Once permissions are correctly set to include your audience, the embed should load for any authenticated user viewing the Sway.

Frequently Asked Questions

Why does my Stream video say 'Refused to connect' when embedded?

This usually happens for two reasons: the viewer lacks the correct permissions in Microsoft Stream to view the video, or the viewer's browser is blocking the third-party cookies required by Stream to verify their login session.

Do viewers need a Microsoft account to watch Stream videos in Sway?

Yes. Microsoft Stream is designed for enterprise and school environments. Viewers must have an active Microsoft 365 account within your organization and be granted permission to view the specific video, even if the Sway presentation itself is shared publicly.

Can I embed a YouTube video in Sway instead of Stream to avoid this?

Yes, Sway fully supports embedding YouTube videos. Because YouTube videos are public and do not require organizational authentication, they generally do not experience 'Refused to connect' errors related to permissions.

Will clearing my browser cache fix the 'Refused to connect' Sway error?

It can. Clearing your browser cache and cookies forces the browser to establish a fresh login session with Microsoft 365, which can resolve authentication misalignments between Sway and Stream.
