VPN, Firewall, and Network Filters: Why Banking Login Can Fail
Disclaimer: Independent informational content. Not affiliated with any bank. No login services. No credential collection.
VPNs and security filters can block the scripts and redirects that modern online banking uses. This may show up as a blank page, infinite loading, or “unable to connect.”
How VPNs can break banking login
- Shared IPs flagged as risky
- Geolocation mismatch
- Encrypted DNS / traffic inspection interference
Safe troubleshooting
- Disable VPN and retry.
- Switch networks (home Wi‑Fi vs cellular).
- If on a corporate network, try at home — enterprise filters may block banking portals.
- Temporarily pause antivirus “web shield” if it breaks trusted sites (then re-enable).
If disabling VPN fixes it, consider adding an exception for the official banking domain (if your VPN supports it).
