QuickBooks Error Code 179 typically occurs when there is an issue with the bank's website or when your login credentials for online banking are incorrect or outdated. Here are some steps you can take to resolve this error:

Verify your login credentials: Double-check that your online banking login credentials (username and password) are accurate. Log in to your bank's website directly using the same credentials to ensure they are working.

Update your bank sign-in information in QuickBooks: If your online banking credentials have changed, you need to update them in QuickBooks. Follow these steps:

- Open QuickBooks and go to the "Banking" menu.

- Select "Bank Feeds" and then "Set Up Bank Feeds."

- Choose the account that is giving you the error and click "Edit sign-in info."

- Enter your updated login credentials and follow the prompts to complete the process.

Check for maintenance or issues on the bank's website: Sometimes, the bank's website undergoes maintenance or experiences temporary issues, causing connectivity problems with QuickBooks. Visit the bank's website directly or contact their support to check if there are any ongoing issues.

Clear cache and temporary internet files: Clearing your browser's cache and temporary internet files can help resolve any temporary conflicts. Depending on the browser you are using, locate the settings or preferences menu and find the option to clear cache and temporary files. After clearing the cache, restart your browser and try connecting with your bank account in QuickBooks again.

Temporarily disable your firewall and antivirus software: In some cases, firewall or antivirus software settings can interfere with the connection between QuickBooks and your bank. Temporarily disable these programs and attempt to connect to your bank account again. If the error is resolved, add QuickBooks to the exceptions or whitelist within your security software to prevent further issues.
