Hello Community,

The Filr 24.4.1 primarily addresses sync issues in the Filr client for Mac. However, it also includes security enhancements that enforce stricter validation of the Host header in incoming HTTP requests on Filr server nodes. The Host header specifies the domain name of the server being requested.

In some scenarios involving load balancers or proxies, the Filr server is accessed by users with a different domain name than that configured on the Filr server. When you install the 24.4.1 in such an environment, you will notice that the users receive HTTP 404 errors when they access the Filr web client:

To enable access to Filr using various domain names, please modify the following configuration in the ssf-ext.properties file:

trusted.domains=filrttp.acme.com

The additional domains can be added in a comma-separated value:

trusted.domains=filrttp.acme.com,filr.ttp.com

**Note:** Please ensure that the ssf-ext.properties file is updated and the Filr service is restarted (rcfilr restart) on every Filr node.
