This error can be caused when there is a firewall or proxy on your network that is scanning attachments to ensure that content with personally identifiable material is not sent outside of the network.
In order to validate if this is an issue on the network or an issue with the application, perform the following steps:
However, if the attachment is being denied by a firewall, you may see a message about the request being denied due to policy, content, etc. This will likely be a firewall on your network denying that request.
This issue can also occur if there is an issue with CMK (Customer Managed Keys), so please let the support person know if your attachments are encrypted using CMK.
