storage.googleapis.com I get "Your connection is not private"

Question

I have a strange error. When I try to load a public blob from Google Cloud Storage in a browser, I get the error "Your connection is not private".

And more strange, when I go to see the certificate, it is emmited to "*.JUEGOILEGAL.ES". For example https://storage.googleapis.com/ysi_production/newsletter-assets/chica_lupa.png

When I'm connected to wifi, there is no problem, but when I'm connected to mobile data, the error appears. I'm trying with some different network operators from Spain, and with some it happens, and others not. For example, with some MásMóvil and Pepephone it happens, with Movistar not.

What happens?

Answer 1

I suggest you try the following things:

• Open the link in Incognito mode
• Clear browser cache and cookies
• Temporarily turn off your antivirus, just to check if there an issue there
• Change DNS settings. For example to the ones provided by Google (8.8.8.8 and 8.8.4.4)
