How does one troubleshoot an "XSRF check failed" error when testing an LDAP connection from the Crowd web app to a Microsoft Active Directory server? I am using Crowd 2.11.0, and we have recently updated the entire company's IP scheme. I have updated all of the hard-coded IPs on the server. It's Ubuntu 16.04.2, Nginx, Postgresql, with Node and Java. I have searched the Atlassian documentation on Crowd, but there is nothing there regarding this error.
Thanks in advance,
Josh
