Hello, @lzhang .
This commonly happens to people who try to access Canvas behind the Great Firewall of China.
I understand that VPN may no longer be an option in the future. Some recent news:
Along with what Nelson said...
This also seems to be something that happens to users of Chrome, where Chrome gets confused if you're on mobile or desktop. This can be confirmed to be a Chrome issue by trying to view Canvas in a different browser.
I'd suggest trying to clear Chrome's cache. If that still doesn't resolve it, contact canvas support who can help you work through some other troubleshooting steps.
Hello @lzhang ...
I noticed that we have not heard from you since you first posted this question back on July 21st, and so I wanted to check in with you. Have you had an opportunity to review the feedback that you've received from @nr2522 , @abunag , and stefaniesanders? If so, did any of their responses help to answer your question? Or, are you still looking for some help with your initial question? If you feel that one of the above replies has helped to answer your question, please feel free to mark it as "Correct". However, if you are still in need of some help with this issue, please come back to this discussion topic to let members of the Canvas Community know so that we can continue to help troubleshoot. I'm hopeful that you've able to get this resolved, and so I'm going to mark your question as "Assumed Answered" because we've not heard from you and because there hasn't been any new activity in this topic for over two months. I hope that's okay with you. Looking forward to hearing back from you soon, Lei!
Hi! I'm also having the same issues with my Canvas account. Images wouldn't load but when I connect to a VPN, they are showing. I'm not sure if it is the problem with the VPN, my browser, or my IP.
