Service Desk Customer Portal Attachments Fail

[Planet Labs]

We just upgraded to service desk 3.0 and JIRA Software. When a user attempts to upload an attachment from the customer portal, they receive the following error:

Cannot attach file: Unknown server error (500).

Here's what I see in the log at the same time:

This happens with any type of attachment and with a number of users. Any ideas?

I once saw a similar case where the problem was related to reverse proxy. Do you have a proxy in front of JIRA? From the error, it seems that the file is being sent as 0 bytes. 

It might be worth to bypass it and see if the problem still reproduces.
