My Rocket.Chat login page shows the URL instead of the page title

My Rocket.Chat login page shows the URL instead of the page title.
I’ve confirmed that the “Site Name” is right at the Administration -> General setup, but it always show the URL at the browser url, I’ve tested on Chrome (71) and Safari (12).

Update: When I refresh the page it quickly changes to the desired Title.

The server version:
