How can i know if the QRCode can be generated?

[AlanBorim]

I´m using the 2FA QRCode to use then Google Authenticator, it works perfectly until now.

Now he show the code, but the QRCode base64 data don´t, with any error ou message to solve, how can i test or adjust the QRCode to show again?

are you seeing any error messages?

what are you using to make the QR code? if it is endroid/qr-code and you've recently updated it, you may need to update this library too

In fact i´m not having any error, just the return of the base64 code of the QRCode came empty, the strange part is until two days ago tha QRCode worked normally

my composer.json is requiring only this

"require": {
    "php": "^8.0",
    "phpmailer/phpmailer": "^6.8",
    "robthree/twofactorauth": "^1.8",
    "vlucas/phpdotenv": "^5.5"
},

And the code that generate the QRCode i´m using this

$secret = $tfa->createSecret();
$qrCodeUrl = $tfa->getQRCodeImageAsDataUri('Test', $secret);

Ah right well you probably want to firstly update to version 2 or 3 of robthree/twofactorauth and then read the docs to pick a different way of making QR codes https://robthree.github.io/TwoFactorAuth/qr-codes.html

Basically, I presume that whatever the default online QR code provider was stopped working or is blocking you so you should switch to one of the offline versions to give you some reliability going forwards.

Also make sure display_errors is on or error_reporting is configured to report errors (note: in development, not production) to ensure that things don't fail silently.
