Could not access Rocket Chat from iOS devices and desktop app on Mac

Description

Hi guys, I just setup RocketChat on Ubuntu 18.04.3 LTS using snap and snap auto SSL.
I was able to access the rocket chat using Chrome and Firefox on Mac, but not safari or the Mac desktop app (Error: “No valid server found at the URL”).
Furthermore, I could not access on the iOS app with this error " Oops! Could not establish a secure connection to the server. Please make sure the server supports SSL."
I was able to connect to the server using the Rocket Chat desktop app for Ubuntu.
