# QR code scanning issues: What could be going wrong?

Encountering problems while trying to scan a QR code? It might be simpler than you think!

One factor to consider is the lifespan of a QR code. Typically, it remains active and ready for scanning only for a brief window of about 1-2 minutes. Missed it? Don't sweat it! Simply hit refresh on your page and give the QR code another go.

If you see an error on your phone about connecting via QR code, but you're sure you scanned it quickly, just do it again as soon as the QR appears on the page.
