I have installed filr 1.01 on VMware ESXi and configured the appliance as standard with the 2nd disk as defined.
Then I start the appliance and give it a IP address etc. The only thing away from simple is that I am using a mask.
Once configured and the prompt tell me to login using - I then get an error with IE, Chrome etc saying

Cannot connect to the real filr.mydomain.net
Something is currently interfering with your secure connection to filr.mydomain.net.
Try to reload this page in a few minutes or after switching to a new network. If you have recently connected to a new Wi-Fi network, finish logging in before reloading.
If you were to visit filr.mydomain.net right now, you might share private information with an attacker. To protect your privacy, Chrome will not load the page until it can establish a secure connection to the real filr.mydomain.net.

I have re-downloaded and re-installed and get the same error.

I have made sure the dns entry is in my DNS as well as the reverse IP

Any ideas?
