Yep. Still having it.
I read firefox's network analyzer reports it as a 500 error, so perhaps it has to do with the Wordpress 500 error?
Here's a screencast.

I have the same problem!
What do we have in common?
I'm using Firefox on ubuntu, but it also happens on android (on various networks).
Maybe their Wordpress installer is malfunctioning?
