I have been using the Goanna build for about a week. Last used KM 76 RC2.

When I attempt to download a report from this site I get this error screen.

Never had this with any of the KM builds going back to 0.7.

Is there some type of security setting that I need to adjust?

I am not a programer - just a content KM user.

Just did a quick search for this prob and the web seems full such stuff.
Perhaps one of those links helps, but no idea:

The TLS version may be the culprit, you can check this on about:config, or use the menu Help>Troubleshoot Prefs for a quick overview of some 'usual suspects' for various probs.

The site uses old encryption methods and old TLS version.
Thats why Goanna can't connect it well.
