Not receiving the warning msg from FMC Interactive block

[nickat]

Hi, I'm running an ESXi hosted Lab.  I've got 3 FTD's managed by an FMC, and I'm using an Elementary OS Linux client to run a browser. 

I've created a rule to interactively block Social Media URL's.  If I select "interactive block",  the web page is stuck loading until it times out. If I select "interactive block reset", I get a an error page that says the webpage is not currently available. In both cases, I'm not getting the warning message from the FMC/FTD.  The HTML response is set to "system generated". Any help will much appreciated. 

Thanks, Nick.

Hi, I've tried System provided and Custom for both Block and Interactive Block. I've had very mixed results. Sometimes I did get the custom message and for the the Interactive Block the button to continue to the website (that just hung and didn't take me on). Other times it just didn't work at all. This is only a training LAB, but it's disappointing not to get consistent functionality, but at least I know how it should work.

Thanks, Nick.

Hi, mixed results again. First attempt to contact Twitter came back with the custom message and continue button, but then reset the connection (as expected). The 2nd attempt was blocked with a "Unable to display this website" msg from the the browser. Any attempts to Facebook just hang on "loading", regardless of settings. 

Thanks, Nick.
