Hello xbrown11,
There are different reasons why you can encounter the 400 Bad Request error. It's possible that:
- You've incorrectly entered the login URL for QuickBooks Self-Employed
- Internet connection is not stable
Make sure you to have a stable internet connection and use this link to log in to your account: https://selfemployed.intuit.com/login.
If the error persists, we can do a few troubleshooting steps. Cache is a component that helps browser's background processes. However, it can also cause issues when piled up. Here's how we can get rid of the cache related issue:
- Open a private browser and log in to your account. It uses but doesn't store cache.
- If you can log in to your account successfully, we can go back to your regular browser and clear the cache.
- You can also use other supported browsers as alternative. Each of them uses different cache.
Keep me posted of the results so we can further help you with this.
