Payment errors in the web-shop check-out can occur for a variety of reasons, including:
- Network issues: Connectivity interruptions, routing errors, or temporary communication failures.
- Web-browser issues: Corrupted cache, cookies, outdated extensions, plug-ins, or conflicting browser configurations.
| Basic troubleshooting |
- Clear your browser data: Clear cache and cookies, then relaunch the browser.
- Try another browser: Preferably use a Chromium-based browser such as Brave, or Google Chrome in Incognito/Private Mode.
- Restart your network equipment: Restart your internet router and any network switches.
- Disable VPNs or proxies: VPNs can interfere with secure payment communication.
- Use a single, stable connection: Disable secondary Wi-Fi networks and, if possible, use a wired Ethernet connection.
- Try a different internet connection: For example, switch to a 4G or 5G mobile network.
- Test another device or computer: Try completing the purchase from a different computer, tablet, or smartphone.
