If the site fails to open, start with the basics: clear your browser cache, disable any extensions that might interfere with scripts, and try a different browser. If the problem persists across browsers, check whether your DNS settings are causing the delay — switching to a public DNS like 8.8.8.8 sometimes resolves it instantly. Also confirm your internet connection is stable before assuming the service itself is down.
Authentication failures usually come down to a few causes:
When a transaction gets rejected, the issue is often on the card issuer's side rather than with Korbank itself. Contact your bank to confirm there are no limits or blocks on online payments. Also verify that the card details — number, expiry date, CVV — are entered without extra spaces. If the payment form freezes mid-process, refresh the page and try again; duplicate charges rarely occur but can be disputed through support.
Outdated app versions are the most common culprit. Update through your device's app store, then restart the app. If it still crashes, clear the app cache in your phone settings without uninstalling — this removes corrupted temporary data while keeping your account information intact.
A transfer sitting in pending status for longer than expected usually means additional verification is required. Log into your account and check whether there is a confirmation request waiting — some transfers trigger a secondary approval step via SMS or email. If no notification arrived, check your spam folder or verify that your phone number on file is current.
Heavy browser tabs competing for memory can make the Korbank interface sluggish. Close unnecessary tabs, especially video or resource-heavy pages running in the background. If performance is consistently poor, test your connection speed — anything below 5 Mbps can noticeably affect how financial interfaces respond, particularly pages that load real-time account data.
