It is assumed that access is restricted on Stream and that the settings to allow access have not been properly configured.
Access to Stream is restricted in a way that allows access to group members, and registration to groups is done by the faculty member.
Immediately after course registration, there is a possibility that the group registration process is not completed in time, or even if it is completed, it may take some time for it to be reflected in the system.
If a faculty member has given you a URL to join a group, please use that URL to apply to join the group. It will take some time because you will not be registered to the group until the faculty member approves.
If there is no such indication, the faculty member will register you again based on the course roster. Therefore, please inform the faculty member that you cannot refer to the video.

“Video not found.”

It is thought that you are not able to sign in to Microsoft365 with the @u.sukuba.ac.jp account.
The solution is the same as below. Please refer to the following for the solution.
