Error Code 377 cant connect my business Credit cards for a week and the error hasn't been resolved.

Hey there, hatzoldconstruct.


Thanks for reaching out here in the Community for support. I want to make sure you're able to connect your business credit cards in QuickBooks Online. 


Receiving error 377 typically means QBO is unable to download transactions for the particular account because the connection type needs to be updated for your Financial Institution. To fix the error, follow the Update Now link from the Banking page. This article offers more information about the error:


While the account is updating, you'll still be able to upload your card transactions into QBO via what's referred to as a Webconnect. To complete this process, you'll first need to download transactions from your bank's website. Here's how:

1. Sign in to your bank's website.
2. Follow your bank's process to download transactions to your computer.
3. Choose transactions from specific or multiple accounts, or select a date range for transactions.
* If you're adding historical transactions for a connected account, make sure to select a date range earlier than the last 90 days. If you overlap date ranges, you may end up with duplicate transactions, which you'll then delete or exclude.

* Because QBO only supports files sizes up to 350 KB (kilobytes), if you're downloading a lot of transactions, you may need to download smaller date ranges.

4. Choose a supported file type for the download file.

Now you're ready to upload the file to your QBO account. This write-up includes the steps to get this done, as well as more information about using Webconnect:


I wish you and your business continued success. Feel free to contact me if you have questions about this process or anything else in QuickBooks. Take care.
