# Allowlisting the CC Platform
*Updated; 10th January 2024*
If your delegates will be accessing the app via a VPN or other secured network, you may need to add some entries to your internal network whitelists for the app to function correctly.
If you are on a secured network and your delegates are experiencing problems accessing the app, please try allowlisting the items below to see if this resolves the issue.
#### Event Platform / App (Front end, user view)

To ensure your customers receive their receipts and payment related emails you will also need to allow list the Stripe Domain '\***@stripe.com**'.
