Virtual-box failed to start VM VERR_INTNET_FLT_IF_NOT_FOUND


When I run vagrant up I get this error

There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

Command: ["startvm", "3ae7b70c-8ea1-417a-ab67-99aef96624f8", "--type", "headless"]

Stderr: VBoxManage.exe: error: Failed to open/create the internal network 'HostInterfaceNetworking-VirtualBox Host-Only Ethernet Adapter #2' (VERR_INTNET_FLT_IF_NOT_FOUND).
VBoxManage.exe: error: Failed to attach the network LUN (VERR_INTNET_FLT_IF_NOT_FOUND)
VBoxManage.exe: error: Details: code E_FAIL (0x80004005), component ConsoleWrap, interface IConsole

I found the solution here: which is to update the driver of VirtualBox Host-Only Ethernet Adapter

But the problem is I am remotely connected to the machine. So I am afraid that the network settings may lose my remote connection. Also, I cannot reboot the machine.

Is it safe to follow the steps mentioned in the link above which should not disconnect me? If not, is there any alternative way?

Recently I have struggled with this issue. I tried many times to solve the issue. Sometimes I was able to run my vagrant machines successfully but how I did was not sure because I was trying lot of options. But finally, I found a way to solve it. It's pretty simple and tricky. Solution:

Once you get this error on your terminal, just open your computer network adaptors from the control panel. Select the adaptor which was created for that virtual box. simply disable once and enable again. then run vagrant up command. That's it. the problem is gone.

Start---> Network status--->Change adaptor options---->(select the Ethrnet'n') then right clik disable and right clik enable. enter image description hereIn my case it is Ethernet4 vagrant up
