As for now we also have an HTML5 client which is a browser client, and this check in tl-setup is not correct. First of it talks about a browser client in plural. And this check is only related to the old java client.
The Browser Clients require a web server with TLS support. No such
server is running on this machine (cannot connect to 127.0.0.1:443).
Most distributions ship the Apache web server in a package called
"httpd", "apache" or "apache2". You might also need the "mod_ssl"
