An error message that reads "Forbidden" may come up when attempting to upload a document. This is usually caused by the web browser being used.
For the best experience using Handshake, we recommend using Chrome or Firefox.
If you're not already using one of these browsers, switch to either Chrome or Firefox and try the upload again.
If you're already using one of these browsers, clear your browser's cache and cookies, then try the upload one more time.
After taking the above troubleshooting steps, if you're still experiencing issues, you can submit a ticket to our Support Team.
