Hello! I have created a simple webapp with a page and an file upload field. But upon selecting a file and then clicking on the upload button, it will always get stuck on the upload step.

When I checked on the network tab of Chrome to see what could be the error, the response from /nl/jsp/uploadFile.jsp is always "Error during authentication". What could be the issue and how do I solve this? I have also tried both anonymous and restricted access. With restricted access, on the login page I will always get the error that my IP address is not allowed access even though it has been whitelisted. Thanks in advance!
