Common Symptoms of the Error
When QuickBooks Error 591 strikes, you'll notice several telltale signs:
- Failed bank feed updates with error notifications
- Inability to download recent transactions from connected accounts
- Repeated login credential requests despite entering correct information
- Frozen screens during bank synchronization attempts
- Missing transaction data in your accounting registers
What Causes QuickBooks Error 591?
Understanding the root causes helps prevent future occurrences. Several factors can trigger QuickBooks Error 591:
Outdated Bank Credentials: Financial institutions frequently update their security protocols. When your stored login information doesn't match the bank's current requirements, the connection fails.
Software Version Issues: Running an outdated version of QuickBooks creates compatibility problems with modern banking APIs and security certificates.
Internet Connectivity Problems: Unstable or weak internet connections interrupt the data exchange between QuickBooks and your financial institution's servers.
Bank Server Maintenance: Scheduled or emergency maintenance on your bank's end temporarily blocks third-party connections.
Corrupted Cache Files: Accumulated temporary files and cached data can become corrupted, interfering with proper bank communication.
Security Software Interference: Overly aggressive firewall settings or antivirus programs may block legitimate QuickBooks banking connections.
5 Easy Steps to Fix QuickBooks Error 591
Follow these proven solutions in order for the best results. Each method targets specific causes of the error.
Step 1: Update Your Bank Credentials
Your first action should be refreshing your banking login information within QuickBooks.
Navigate to the Banking menu and select the affected account. Click on the pencil icon or "Edit" option next to your bank connection. Enter your current online banking username and password, ensuring you're using the exact credentials that work on your bank's website.
Many users overlook special characters or case sensitivity when entering passwords. Double-check each character before saving. If your bank recently implemented multi-factor authentication, you'll need to complete that verification process within QuickBooks.
After updating credentials, attempt to refresh your bank feed. This simple action resolves QuickBooks Error 591 in approximately 40% of cases.
Step 2: Update QuickBooks to the Latest Version
Software updates contain critical patches and improvements for banking connectivity.
Open QuickBooks and access the Help menu. Select "Update QuickBooks Desktop" or check for updates through your settings. Allow the software to download and install all available updates completely.
This process ensures your application has the latest security certificates and banking protocols required by financial institutions. After updating, restart your computer to ensure all changes take effect properly.
Keeping your software current prevents many banking errors, including QuickBooks Error 591, from occurring in the first place.
Step 3: Verify Your Internet Connection
A stable internet connection is essential for banking operations.
Test your connection speed using an online speed test tool. You need at least 1 Mbps for basic QuickBooks banking functions, though 5 Mbps or higher is recommended.
If using Wi-Fi, try switching to a wired Ethernet connection for more stability. Restart your router and modem by unplugging them for 30 seconds, then plugging them back in.
Check if other applications can access the internet properly. If you're experiencing widespread connectivity issues, contact your internet service provider before proceeding with other troubleshooting steps.
Step 4: Clear QuickBooks Cache and Temporary Files
Corrupted temporary files often cause persistent connection problems.
Close QuickBooks completely. Press Windows Key + R to open the Run dialog box. Type "%temp%" and press Enter. This opens your temporary files folder.
Select all files in this folder and delete them. Some files may be in use and cannot be deleted – this is normal, skip those files.
Next, clear QuickBooks-specific cache. Open QuickBooks, go to Edit, then Preferences. Select "Integrated Applications" and click on "Company Preferences." Remove any applications you don't recognize or use.
Restart QuickBooks and attempt your bank connection again. This process eliminates corrupted data that may be blocking proper communication with your financial institution.
Step 5: Disconnect and Reconnect Your Bank Account
When other methods fail, completely resetting your bank connection often resolves QuickBooks Error 591.
Go to the Banking menu and select "Bank Feeds." Find your problematic account and choose "Deactivate Bank Feed" or "Disconnect." Confirm the disconnection.
Wait approximately 5 minutes before reconnecting. This pause allows QuickBooks servers to fully process the disconnection.
Click "Add Account" or "Connect Bank" and search for your financial institution. Follow the prompts to establish a fresh connection with your current credentials.
This clean slate approach eliminates any corrupted connection settings that may have been causing the error.
Advanced Troubleshooting for Persistent Issues
If QuickBooks Error 591 persists after trying all five steps, consider these additional measures:
Check Bank Website Functionality: Log directly into your bank's website to ensure their online banking system is operational. Sometimes the issue originates from the bank's end rather than QuickBooks.
Configure Firewall Settings: Add QuickBooks as an exception in your firewall and antivirus software. These security programs sometimes block legitimate banking connections.
Run QuickBooks File Doctor: This diagnostic tool identifies and repairs data file corruption that may be contributing to connectivity problems.
Contact Your Bank: Financial institutions occasionally change their third-party access policies. Verify that QuickBooks connections are still permitted and properly configured on their system.

Frequently Asked Questions
Q1: How long does it typically take to fix QuickBooks Error 591?
Most cases resolve within 10-15 minutes using the basic troubleshooting steps. If you need to update QuickBooks software or clear extensive cache files, the process might take 30-45 minutes including download and restart time.
Q2: Will disconnecting my bank account delete my existing transactions?
No, disconnecting and reconnecting your bank feed does not delete previously downloaded transactions. Your historical data remains safe in QuickBooks. Only the live connection is reset, and you can immediately begin downloading new transactions after reconnecting.
Q3: Can I use QuickBooks while experiencing Error 591?
Yes, you can continue using most QuickBooks features during this error. Only banking functions—such as downloading transactions and updating bank feeds—are affected. You can still create invoices, enter bills, run reports, and perform other accounting tasks.
Q4: Is Error 591 specific to certain banks or financial institutions?
No, QuickBooks Error 591 can occur with any bank or financial institution. However, it may appear more frequently after your bank implements security updates or changes their online banking platform. The error is related to the connection protocol rather than specific institutions.
Q5: How often should I update my QuickBooks software to prevent banking errors?
Check for updates at least monthly, though enabling automatic updates is the best practice. Intuit releases updates regularly to address security vulnerabilities and maintain compatibility with banking systems. Staying current significantly reduces the likelihood of encountering QuickBooks Error 591 and similar issues.
Q6: What should I do if my bank isn't listed when trying to reconnect?
If your financial institution doesn't appear in the search results, try searching by different name variations or abbreviations. Some banks operate under multiple names or have merged with other institutions. Alternatively, use the "Manual" connection option to enter your bank's information directly, or contact QuickBooks customer care for assistance.
