Hello. Matheu Silveira, some steps need to be taken to identify why Whatsapp QrCode is not appearing in your browser.
One of the crucial factors is the application of end-to-end encryption for WhatsApp conversations, which prevents SSL inspection to ensure the proper functioning of WhatsApp Web or app.
To prevent interruptions, it is essential to select the 'Instant messaging change' category as an exception if there is an SSL profile in the policy. This measure is crucial, since one of the main reasons for not transmitting or receiving messages, as well as the absence of QR Code when accessing the web, is related to this configuration.
