Try Opera browser with a built-in VPN. It might help. I remember it helped me once when I had trouble accessing a website from Vietnam.
I am still Vietnam but, I guess, the hostel of the internet provider of the hostel has an included VPN - everything works fine without VPN here.
Thanks. I will try it.
Happy Lunar New Year and enjoy Tet in Vietnam.
Thank you! Happy Lunar New Year! Enjoy the holiday!
