I'm a student in DEC5 S-L (01).When I do my homework on Academic skills Paraphrasing，the web looks like this.
Hi yu zhao and welcome to the Canvas community. This is a global community of Canvas users from different institutions where we discuss our experiences and share tips on the use of Canvas. Therefore we don't have access to Canvas content at your university to check what's causing the problem, but looking at your screenshot I would guess that the teacher of this course has added a link to a file or page that has not yet been released to students. You should contact the course teacher or your university's technical support team and report the problem to them.
Hello yu zhao and welcome to the Canvas Community. That error message an appear for several reasons such as the page/resource you are trying to access not being published, the link you are using actually being for a course in which you are not enrolled (such as a previous section of the course), etc. The best option would be to contact your instructor, the Canvas support group at your institution, or Canvas Support through Instructure directly (using the help question mark icon). Any of these individuals would be able to look specifically at your class and this resource and see what is causing the problem. The fix may be relatively simple, but probably will require the instructor making a change on their end or or providing an update link.
I hope this helps and best wishes!
