Temporary failure in name resolution after installing VirtualBox 6.1.34

[YevheniiPokhvalii]

Version

0.58.3.0

WSL Version

• WSL 2
• WSL 1

Kernel Version

5.10.102.1

Distro Version

Ubuntu 22.04

Other Software

VirtualBox 6.1.34

> wsl --status
Default Distribution: Ubuntu
Default Version: 2
WSL version: 0.58.3.0
Kernel version: 5.10.102.1
WSLg version: 1.0.33
MSRDC version: 1.2.2924
Direct3D version: 1.601.0
Windows version: 10.0.22000.675

Repro Steps

1. Install VirtualBox 6.1.34
2. Reboot the system
3. Enter WSL
4. ping google.com

Also, I am able to ping 8.8.8.8, I can ping my router gateway from WSL, but I can't ping the automatically assigned nameservers by WSL:

$ cat /etc/resolv.conf | grep -B 1 nameserver
# generateResolvConf = false
nameserver 172.17.192.1
$ ping 172.17.192.1
PING 172.17.192.1 (172.17.192.1) 56(84) bytes of data.

I tried solutions with firewalls but it did not help: #4171 (comment)
The solution with sudo bash -c 'echo "nameserver 8.8.8.8" > /etc/resolv.conf' works but it does not work when I enable VPN which I do quite often.

The issue happened just right after I installed VirtualBox. Uninstalling VirtualBox did not help.
Also, I tried to re-enable Hyper-V - still not result.
Network flush did not help either: #3438 (comment)

Expected Behavior

I am able to ping google.com

Actual Behavior

$ ping google.com
ping: google.com: Temporary failure in name resolution

It seems to be working with VPN when I add my WIFI router gateway IP as a nameserver to WSL:

> netsh interface ip show config "WiFi"

Configuration for interface "WiFi"
    DHCP enabled:                         Yes
    IP Address:                           192.168.0.106

    Gateway Metric:                       0
    InterfaceMetric:                      50
    DNS servers configured through DHCP:  192.168.0.1
    Register with which suffix:           Primary only
    WINS servers configured through DHCP: None

sudo bash -c 'echo "nameserver 192.168.0.1" > /etc/resolv.conf'
