Wireguard WireQuard Device QR Code won't Scan from iPhone

[Chewie420]

Hello I was troubleshooting my router and removed wg and now I am trying to get it working again.

I have wg installed and Server has been started. When I try to scan the QR code using WireGuard app on my iPhone nothing happens. I know I did it before but I can't remember for the life of me how to export my config for my device that I created.

not sure where to find it and now even when I click on option 7 to view QR code I am getting an error that says
***ERROR Missing/invalid Peer config

You need to specify the name of the 'device' Peer...

e.g. List ALL peers....

E:Option ==> peer

So to display the QRCode for a specific Road-Warrior 'device' Peer from the list of devices
e.g.

e  = Exit Script [?]

E:Option ==> 7 SGS20_5G

To use the QRCode to import the profile on the iPhone...

• In the WireGuard iOS app, tap “Add a Tunnel”, or tap the plus symbol at the upper right corner.
• In the dialog, tap “Create from QR code”. (Allow the WireGuard app to use the camera.)
• When the camera activates; point the camera at the QR code.
• Name the tunnel and tap “Save”. (Allow the WireGuard app to add VPN configurations.)

If scanning a QRCode is not practical, you can export the necessary profile from directory '/opt/etc/wireguard.d/'

• e.g. '/opt/etc/wireguard.d/iPhone.conf' and import the file into the WireGuard iOS app.

Hi Thanks for you message, I got the QR Code to display but it is so large it takes up more than the screen can display and I am unable to scan it with my phone.


Can you tell me where the file can be exported from?

Using either Xshell orMobaXterm allows you to dynamically make the QRCode fit on screen by using CTRL+ScrollWheel?

However you should be able to export the file from '/opt/etc/wireguard.d/iPhone.conf'

I usually do it the old fashion way, I take my camera and backup however much distance is required to get the QR small enough.
