Hi,
We have updated this function to be configurable and it will now default to the api.qrserver.com service.
To use a different service, a user.config setting like the following will need to be set.
<add key="QRCodeGeneratorUrl" value="https://api.qrserver.com/v1/create-qr-code/?size={0}x{1}&format={2}&data={3}" />
We will likely replace this soon with a built-in generator so we aren't reliant on 3rd party sites.
The code for this was in Web/Controls/Google/QRCodeImage.cs. We are moving it to Web/Controls/QRCodeImage.cs.
Thank you,
Joe
