I disabled security warning in Java Control panel, under Advanced, Security, General, “Warn if the site certificate does not match hostname”.

I tried that and still received the warnings.

However, in the java control panel under Advanced -> Security -> Mixed code I changed the setting to "Enable - hide warning and run with protections"

Now the warnings no longer appear.

Thanks for pointing me in the right direction.

no problem, it was one of those settings. I disabled/enabled a bunch of them trying to make that pop-up go away
