Question

Clientas reales bloqueadas al reservar – error de seguridad "This booking cannot be completed"

Hi Calendly Support,
I'm writing about an ongoing issue with my account. Several of my real, returning clients are being blocked when they try to book an appointment. They used my scheduling page without any problem before, and now it fails.
 

What clients see:
    •    The page keeps loading and no available times appear.
    •    After a few minutes it asks them to refresh the session, and the same thing happens again.
    •    Finally they get this message: "This booking cannot be completed. For security reasons, we are not able to finalize this booking from your current session."
Error code shared by one of my clients:
tid-rb-236ac2a3-a91f-40fe-b157-0d2a33476e63
It is happening to several clients, some of them coworkers who may be booking from the same network. They are genuine clients, not spam.
 

This is affecting my business directly, since clients cannot book their appointments. Thank you for your help.
Best regards,
Sofía Zabala
