QuickBooks Error 105 often stems from basic connectivity issues that prevent the software from reaching bank servers. Steps to check: <ul> <li style="font-weight: 400;">Open your web browser and visit multiple websites</li> <li style="font-weight: 400;">Run a speed test to confirm adequate bandwidth</li> <li style="font-weight: 400;">Restart your router and modem</li> <li style="font-weight: 400;">Disable VPN services temporarily</li> <li style="font-weight: 400;">Switch to a wired connection if using Wi-Fi</li> </ul> A stable internet connection forms the foundation for successful bank feed updates. If connectivity issues persist, contact your internet service provider before proceeding. <h2>Method 2: Update QuickBooks to the Latest Version</h2> Outdated software versions frequently trigger QuickBooks Error 105. Intuit regularly releases patches that improve banking connectivity and fix known bugs. For QuickBooks Desktop: <ul> <li style="font-weight: 400;">Navigate to the Help menu</li> <li style="font-weight: 400;">Select "Update QuickBooks Desktop"</li> <li style="font-weight: 400;">Click "Update Now" and mark all updates</li> <li style="font-weight: 400;">Select "Get Updates" to download</li> <li style="font-weight: 400;">Restart QuickBooks after installation completes</li> </ul> For QuickBooks Online: The platform updates automatically, but clearing your browser cache ensures you're accessing the latest version. Use fresh browser sessions to avoid cached data conflicts. <h2>Method 3: Clear Browser Cache and Cookies</h2> Corrupted cache files commonly cause QuickBooks Error 105 in QuickBooks Online. These temporary files can interfere with the authentication process between your browser and banking institutions. Clearing cache in Chrome: <ul> <li style="font-weight: 400;">Click the three-dot menu icon</li> <li style="font-weight: 400;">Select "More tools" then "Clear browsing data"</li> <li style="font-weight: 400;">Choose "All time" as the time range</li> <li style="font-weight: 400;">Check "Cookies" and "Cached images"</li> <li style="font-weight: 400;">Click "Clear data" to complete</li> </ul> After clearing cache, restart your browser completely before accessing QuickBooks again. This ensures a clean session without residual data. <h2>Method 4: Disconnect and Reconnect Your Bank Account</h2> Refreshing the connection between QuickBooks and your financial institution often resolves QuickBooks Error 105. This process establishes new authentication credentials and clears any corrupted connection data. Reconnection process: <ul> <li style="font-weight: 400;">Log into your QuickBooks account</li> <li style="font-weight: 400;">Navigate to Banking or Transactions</li> <li style="font-weight: 400;">Locate the problematic account</li> <li style="font-weight: 400;">Click the pencil icon or Edit</li> <li style="font-weight: 400;">Select "Disconnect this account"</li> <li style="font-weight: 400;">Wait five minutes for server synchronization</li> <li style="font-weight: 400;">Add the account again using current credentials</li> </ul> This method forces QuickBooks to establish a fresh connection with updated security protocols and authentication tokens. <h2>Method 5: Verify Bank Login Credentials</h2> Incorrect login information frequently triggers QuickBooks Error 105. Banks regularly require password updates or implement new security measures that affect third-party application access. Credential verification steps: <ul> <li style="font-weight: 400;">Visit your bank's website directly</li> <li style="font-weight: 400;">Log in using your current credentials</li> <li style="font-weight: 400;">Complete any pending security updates</li> <li style="font-weight: 400;">Enable third-party application access in settings</li> <li style="font-weight: 400;">Check for any notifications about account access</li> <li style="font-weight: 400;">Update your password if prompted</li> </ul> Some financial institutions require explicit permission for QuickBooks to access your accounts. Navigate to your bank's security settings and authorize QuickBooks as a trusted application. <h2>Method 6: Configure Firewall and Security Settings</h2> Overly restrictive firewall settings can block QuickBooks from communicating with bank servers, resulting in QuickBooks Error 105. Security software sometimes classifies banking connections as suspicious activity. Firewall configuration: <ul> <li style="font-weight: 400;">Open Windows Security or your antivirus program</li> <li style="font-weight: 400;">Navigate to Firewall settings</li> <li style="font-weight: 400;">Add QuickBooks to allowed applications</li> <li style="font-weight: 400;">Create inbound and outbound rules for QuickBooks</li> <li style="font-weight: 400;">Restart your computer after changes</li> </ul> Ensure Windows Defender or third-party security software doesn't quarantine QuickBooks processes. Temporarily disable these programs to test if they're causing the error. <h2>Method 7: Contact Your Bank's Technical Team</h2> When technical methods fail to resolve QuickBooks Error 105, the issue may originate from your bank's end. Financial institutions occasionally experience server maintenance or implement system updates that temporarily disrupt third-party connections. What to ask your bank: <ul> <li style="font-weight: 400;">Are there current system maintenance activities?</li> <li style="font-weight: 400;">Has my account been flagged for security reasons?</li> <li style="font-weight: 400;">Do you have specific requirements for QuickBooks access?</li> <li style="font-weight: 400;">Are there recent policy changes affecting third-party apps?</li> </ul> Banks can provide specific error codes or system status information that helps pinpoint the exact cause of QuickBooks Error 105.
