The network and reverse proxy settings that you configure after installing Filr affect how email notification URLs are constructed. If you have configured port redirection and have failed to verify the reverse proxy ports, email notifications from Filr can be constructed in such a way that users who click on the email notification URL are not able to access the Filr site.
When port redirection is enabled (as described in Using the Network (Port Redirection) dialog
in the Filr 4.3: Administrative UI Reference.), ensure that the reverse proxy ports are set to 80 for the HTTP port and to 443 for the secure HTTP port. To change the reverse proxy ports, see Reverse Proxy Configuration Settings
in the Filr 4.3: Administrative UI Reference.
