Greetings,

Looking at the output and searching explicitly for Cannot read registry key SYSTEM\CurrentControlSet\Control\Network\{4D36E972-E325-11CE-BFC1-08002BE10318}\{5E285114-0E5C-4AB1-BFBB-541B0700518F}\Connection\Name or is not string this looks to be an issue with openconnect itself. As I do not want to link an external website- the first entry on google searching this phrase seems to exhibit the same issues that you are observing and may be associated with your problem. You may need to inquire on the openconnect gitlab site for further support as this appears to be specific to openconnect code.

In OpenConnect VPN window edit your current profile or setup a new one, under (advanced) settings rename (interface name) to something simple. I had a very similar issue, hope this helps.

@Chandran are you using windows here? I saw few past thread with this not working, and when the user switched to anyconnect this was ok.

It worked when I edited my profile in OpenConnect and added "mvpn" in local interface.

Hi @Chandran ,

Apologies for the delay getting back to to you. Glad you got this sorted.

I've had the same issue: Set up tun device failed

Here is detailed step on what worked for me:

Under Profiles -> Edit selected profile -> Interface name, put "myvpn"
