What Is QuickBooks Error 179?

QuickBooks Error 179 is a bank-related error that occurs when QuickBooks fails to connect with the bank's server. When this error arises, QuickBooks may be unable to retrieve data from your bank account, thus preventing users from performing important functions such as downloading bank transactions or updating account information.

You may encounter an error message that states:

> “Error 179: Bank Connection Lost. Please try again later.”

This error can be particularly frustrating, as it disrupts critical financial processes like reconciliation and account updates. Understanding the root causes of this issue is key to fixing it efficiently.

Symptoms of QuickBooks Error 179

When QuickBooks Error 179 occurs, you may notice one or more of the following symptoms:

1. Bank Login Failures: You may be unable to log into your bank account through QuickBooks, even with the correct credentials.
2. Missing Transactions: After the error occurs, previously downloaded bank transactions may appear missing from your QuickBooks records.
3. Discrepancies in Reconciliation: Due to missing or incorrect transactions, your account reconciliation may fail or show discrepancies.
4. QuickBooks Freezing: The software may become unresponsive or crash while trying to connect to the bank.
5. Incomplete Download of Bank Data: Bank transactions may not be downloaded in full or may not update in QuickBooks after the error occurs.
6. System Lagging: You may experience lagging or slowness in QuickBooks during online banking activities.

Common Causes of QuickBooks Error 179

Several factors can trigger QuickBooks Error 179, and identifying the correct cause is the first step to resolving the problem. 

Below are the most common reasons why this error may occur:

1. Incorrect Bank Login Credentials: One of the most frequent causes of QuickBooks Error 179 is entering the wrong login credentials (username and password) when trying to access your bank account through QuickBooks. If QuickBooks detects an incorrect login attempt, it will block the connection, resulting in the error.
2. Multiple Logins on Different Devices: If you’re logged into your bank account on multiple devices (such as a smartphone, tablet, or another computer), your bank may flag it as suspicious activity and block access. This security measure is intended to prevent unauthorized access to your account, but it can also cause QuickBooks Error 179.
3. Browser Cache or Cookies Issues: Corrupted or outdated cache and cookies in your browser can interfere with QuickBooks’ ability to connect to your bank account. Cache and cookies store temporary information that sometimes conflicts with QuickBooks, leading to Error 179.
4. Outdated QuickBooks Software: Running an outdated version of QuickBooks can contribute to various errors, including Error 179. QuickBooks periodically releases updates that fix bugs and improve compatibility with bank servers. Failing to update QuickBooks can result in connection issues when attempting to log into your bank.
5. Bank Server Downtime: Occasionally, the bank's server may be down for maintenance or experiencing technical issues. If the bank server is unavailable, QuickBooks cannot establish a connection, and Error 179 may occur.
6. Corrupted QuickBooks Company File: A corrupted or damaged QuickBooks company file can lead to banking errors, including Error 179. If QuickBooks cannot properly access the company file, it may encounter difficulties when trying to download or sync banking transactions.
7. Blocked Access by Security Software: Firewall, antivirus, or other security settings on your computer may block QuickBooks from connecting to your bank. Overly strict security measures may mistakenly flag QuickBooks as a security threat and disrupt the connection to the bank's servers.

Pre-Solution Checklist

Before jumping into solutions, ensure that the following items are to avoid unnecessary troubleshooting:

1. Stable Internet Connection: Verify that your internet connection is stable and not causing issues with online banking in QuickBooks.
2. Correct Bank Login Credentials: Double-check that you are entering the correct username and password for your bank account.
3. Check Bank Website: Visit your bank’s website directly to verify whether the server is down or undergoing maintenance.
4. Log Out from Other Devices: Ensure that you are not logged into your bank account on multiple devices.
