I can upload files to the server in my application, I use angular in the front-end I'm using this library to upload files ng2-file-upload, and I'm using Spring boot in the backend, for the moment it works fine for files up to 1GB, however for even bigger files I got this exeception while uploading :

It's seems that while uploading the server recieved a null request but I'm not sure, can anybody explain this error?
To invastigate this issue you can do following:
1. Add server.connection-timeout=-1 property to application.properties and check if the error appears (-1 means infinite timeout)
2. Try to deploy war on standalone tomcat (as far as i know sometimes it behave diffrent that embedded into springboot)
