What Is Error E55?

Error E55 in the BNA+ app or at an ATM means that the transaction could not be processed. Importantly, it doesn’t necessarily indicate an issue with your account or funds—it’s often a technical or communication error.

Common Causes

This error can happen due to several underlying factors:

• Unstable or weak internet connection, interrupting the app’s communication with bank servers

• Temporary server-side issues at Banco Nación

• Outdated or corrupted app version

• Incorrect transaction inputs (e.g., wrong amounts, account details)

• Insufficient account balance or exceeding per-day transaction limits

• Corrupted app data or lack of device storage
