February, 2020 update:

Chime and Ally are experiencing technical issues that prevent NerdWallet members from linking accounts from those banks. A fix is underway but at this time we can't offer an estimate for when it will be available.

We'll update this article as soon as these issues are resolved.  

***

If you’re seeing an error message when you try to link your bank account to your NerdWallet account, there are a few possible causes. We’re happy to help troubleshoot the issue, but will need some details from you about what you’re experiencing since we can only see a limited amount of information about your NerdWallet account on our end.

Send us an email at support@nerdwallet.com that includes the following information and we’ll do our best to find a solution:

• The name of the bank and type of account you’re trying to link (checking, savings, credit card, etc.)
• The exact text of the error message you’re receiving. Screenshots of what you’re seeing can be helpful as well.
