If you use VPN, proxy server or third-party firewalls (for example, NetGuard, AdGuard), they can block the connection Sberbank Online with the bank's servers. Moreover, the blocking may only occur on mobile data, not Wi-Fi.

Banks use geolocation to protect against fraud. If your IP address suddenly changes (for example, from Moscow to the US), the system perceives this as suspicious activity and may block access.
