I have an application (writen in React.js) that works perfectly in Chrome Browser on my computer.

When I try to load the app on my phone with Chrome, the app loads well when I am in Wifi but not when I am in my mobile network (4G).

I have a perfectly valid SSL certificate created with Let's Encrypt.

Do you have an idea why ?

  • Yes, I have no informations. It says that "No security details are available for this origin.". I have an ERR_TIMED_OUT error. When i activate my Wifi connection, it works. If I share my 4G connection and connect with my computer in Wifi to my 4G mobile data it also works. That's no sense –  Feb 20 '20 at 09:35
  • The IPv6 of my server had changed. I upated my DNS AAAA record and it works now. –  Feb 20 '20 at 12:19
