 Replying to [comment:6 sbr1115]:
 > the problem is NOT a specific theme or plugin in MY case. It doesn't
 work with any. All plugins were off. I do not understand why I can not see
 any theme active or not with live preview. When I first started with all
 of this it was working fine. Nothing changed from the time it worked to
 the next time I went to use it.

 Something did change, but it was likely something in the server config
 that was changed without your knowledge, or a plugin update and the plugin
 was active. Can you check your browser console to see if there are any
 errors? If this is a core issue, it's likely that it's the same as in
 #22037, but I'm guessing its some bad code in a plugin that's causing
 something like a 500 server error in the Customizer preview in your
 environment.
