Problem

Getting an error "Submit Failed, Please try again" when trying to upload a file for a submission of an assignment in Canvas. 

Solution

There can be several potential issues causing this problem. Please try the below steps and if you still see the issue, contact the IT service desk. 

• Clear your browser cache and cookies - Sometimes the collection of web page data stored on your computer can cause issues. Clearing your cache forces the browser to use the newest data available from Canvas.
• Try a different browser - To ensure the issue is not related to the browser you are using, please attempt the upload using a different browser. This can assist in troubleshooting by identifying if the issue is browser specific.
• Use an incognito/private window - You may find that using the incognito or private mode for your browser can help to “turn off” any browser plugins or extensions and/ or may avoid issues related to browser cache and cookies. Attempt your upload in the incognito or private browser mode and see if this makes a difference.
• Check the file size of the file intended for upload - Canvas has the following file upload limits: 

Note: If file compression is required and you compress it to less than 5GB and it still fails, then please attempt the same file upload again using either an incognito/private browser window or clearing your browser cache.
