Briefly: if Yandex services aren't working in Vietnam, change your DNS to Google's—8.8.8.8 and 8.8.4.4—in your router or device's network settings. If that doesn't help, the problem isn't with your DNS, but with geolocation restrictions—in which case a VPN might help.

Setting Up Google DNS: A Step-by-Step Guide
If you have problems accessing Yandex services, changing DNS servers to more stable ones, such as Google DNS, often helps. Below is a detailed instruction on how to do this both on the router and directly on the computer.
1. Setting up on the router
Step 1. Login to the router control panel
Open your browser and enter the IP address of your router (usually 192.168.1.1 or 192.168.0.1; check the case or documentation for details).
Enter your login and password (by default, often admin/admin, if not changed).
Step 2: Find DNS settings
Find the "Internet", "WAN", "Network" or "Connection Settings" section.
Look for the fields for DNS servers - they may be filled with your ISP's addresses.
Step 3. Replacing DNS
In the Primary DNS field, enter 8.8.8.8.
(Optional) In the secondary field – 8.8.4.4.
Save the settings. If necessary, reboot the router.
2. Setting up on a computer
If you don’t have access to your router settings, you can change the DNS directly on the device.

Open Control Panel → Network and Sharing Center.
Click "Change adapter settings". See the image below.
Right-click on the active connection and select Properties.

Alternative DNS: 8.8.4.4
Click "OK" to save the changes. See the image below.
