Hmm, there might be an implicit maximum file size imposed by Jetty, though I would expect that to trigger something in the logs. Are these file uploads being triggered on a desktop computer, or a mobile device? Any chance you could wireshark the upload request?

There's some configuration you can do to Jetty, though again, I'm not sure this is even the source of the problem:

In $IGNITION/webserver/webapps/main/WEB-INF/web.xml there’s a section like this: \<servlet\> \<servlet-name\>DataRoutes\</servlet-name\> \<servlet-class\>com.inductiveautomation.ignition.gateway.dataroutes.DataServlet\</servlet-class\> \<load-on-startup\>1\</load-on-startup\> \<multipart-config\> \<max-file-size\>20848820\</max-file-size\> \<max-request-size\>418…
