Remote "" is unknown or unreachable in windows
Describe the bug multipass launch get errors as follows:
[2022-05-04T20:04:02.964] [error] [workflow provider] Error fetching Blueprints: failed to download from 'https://codeload.github.com/canonical/multipass-workflows/zip/refs/heads/main': Error opening https://codeload.github.com/canonical/multipass-workflows/zip/refs/heads/main
launch failed: Remote "" is unknown or unreachable.
To Reproduce I install multipass 1.9.0, and then multipass launch
Expected behavior Why I cannot launch a instance? I can open url. Last three or four month ago, I use multipass(1.7.0), it's ok. My os is the same as before. Logs
Additional info
- OS: [Windows 10 1904
- Multipass: 1.9.0+win
-
multipass info --allno output --VPN app is letsVPN, 3.2.5; this tool has no port to set?
Additional context no
Hi @hengaini2055! It seems Multipass cannot access the network, the VPN being the most probable cause. Can you please try to connect without using the VPN?
I look at https://multipass.run/docs/troubleshooting-networking-on-windows, the problem is still. I connect without using the VPN， the issue is the same. @luis4a0
Same happens for me under Ubuntu 22.04:

Multipass 1.9.2 from the stable-channel does produce this error, Multipass 1.8.0 from the candidate-channel still works. Multipass 1.10 from the edge-channel also works.
Here is my log-file:
I've installed "snapcraft" and "multipass" after rebooting the system. One strange thing also happens frequently:
When i use "multipass" my network-connection gets broken. Multipass seems to break the DNS-configuration. Disconnecting and reconnecting my WIFI always helps.
Edit:
I've found the cause of my problem:
I've activated a LAN-connection in Netplan and it seems that multipass always tries this connection even if the cable is disconnected and another connection is available.
Hey @glasen,
So there is an issue in QtNetwork that was fixed and seems to have regressed somewhat recently when switching networks: https://bugreports.qt.io/browse/QTBUG-55180
I have met the same problem. On my macbook access is normal. On windows, it will report this error, they are connected to the same network, mutipass version is 1.9.1
Having same issue on Ubuntu 22.04. By running sudo journalctl --unit 'snap.multipass*'
Looking at the output below, it appears that Multipass is performing some check to see if there is an active network connection on the host. The odd thing is that I DO have a working network connection (through NetworkManager). I wonder if maybe it just has a different name. I don't know enough about the system (dbus?) being used to query the active connections so can't confirm what the network connections are known as on my system. Maybe Multipass has hardcoded a name of "1"?
I have confirmed that I can access all the URLs in the logs below via curl without issue.
Thanks, Nick

I've just tried to launch a new instance and I'm seeing the same problem using multipass 1.11.0 on Linux Mint 21.1 with Cinnamon 5.6.8.
