Last, but not least, we have a solution that might appear strange at first sight, but it may just be the most reliable fix to date.
Apparently, after some meddling with the installation and associated network drivers tinkering, users managed to find the resolution.
First of all, you need to start Hamachi and make sure it’s running.
After that, head over to your Device Manager and uninstall all LogMeIn virtual ethernet drivers (in the Network adapters section).
Once you’ve dealt with drivers, just reinstall Hamachi again (method 2) and everything should get back to normal.
This fix is quite peculiar indeed, but hey, at least it gets the job done.
All things considered, if your Hamachi client prompts you with the VPN domain’s tap device is down error, there are a few ways you can fix it.
We recommend you to try each of our methods, one at a time. We’re quite confident you’ll restore Hamachi‘s functionality in no time.
