streamed content stops in screen sharing

When I attempt to share my streamed video content, such as from YouTube or online video clips, the clip will play for a few seconds, then stop. I can restart it, but it stops again. The clip actually stops. The video control button on the app switches from stop to play. This only seems to happen on one zoom meeting. I have been able to play videos on other meetings. Are there settings or rights i need to be assigned? I am functioning as a cohost during these meetings. Thanks.
