Why the checkout appears to get "stuck in processing"
rather than showing an error message.
Causes of Checkout Freezes
- Poor mobile network signals causing data timeouts during payment submission.
- Outdated app or browser versions failing to load security scripts.
- Browser extension conflicts blocking security or tracking tokens on desktops.
When the security software blocks the payment,
your checkout page is waiting for a response from the payment processor that will never arrive
because the security software prevented the information from being sent in the first place.
The page doesn't know it was blocked,
so it just keeps waiting indefinitely,
which looks to the customer like it's frozen or stuck.

temporarily disabling
any VPN,

then try again.
And here is a more extensive LIST of things that might be the problem
Security software often blocks online checkouts by interfering with the hidden scripts and encrypted connections required to verify payment details.
The following security settings are the most common culprits:
1. Payment & Banking Protection Modes
Many antivirus suites include "Safe Pay" or "Hardened Browser" modes that isolate financial transactions. While protective, they can prevent checkout pages from communicating with external payment gateways like Stripe or PayPal.
- Software Examples: Bitdefender Safepay, Kaspersky Safe Money, or Trend Micro Pay Guard.
- The Fix: Try disabling the specialized banking protection temporarily or use a standard browser window to see if the transaction proceeds.
2. Script & Ad Blocking
Checkout systems rely on JavaScript to securely send your card data to the processor without it ever touching the merchant's server.
- Browser Extensions: Tools like uBlock Origin, NoScript, or built-in browser "Strict" tracking protection may block these scripts as potential trackers.
- The Fix: Ensure JavaScript is enabled in your browser settings and whitelist the merchant's domain in your ad-blocker.
3. Firewall Port & Domain Restrictions
Corporate or highly restrictive personal firewalls may block the specific TCP/UDP ports used for encrypted financial data.
- Domain Blocking: Firewalls sometimes block third-party domains (e.g.,
stripe.comorbraintreegateway.com) that are embedded in the checkout page. - The Fix: Check your Windows Firewall settings to ensure it isn't blocking outbound traffic to payment providers.
4. Clipboard & Screenshot Protection
Some security software blocks applications from accessing your system clipboard to prevent malware from stealing copied card numbers.
- The Problem: If you are using a password manager or copying your card number, the security software may "blank" the data during the paste process.
- The Fix: Manually type the card information instead of using copy-paste.
5. Virtual Private Networks (VPNs)
VPNs change your IP address, which may trigger fraud detection systems on the merchant's end if your digital location doesn't match your billing address.
- The Fix: Temporarily disconnect your VPN or switch to a server located in your home country.
