We can troubleshoot this issue to ensure you can log into your QuickBooks account using your desktop, ajijoinery.
Before we proceed, could you let me know if you've encountered any specific error messages while attempting to access your account? This information will allow us to provide the most effective solution for your issue.
In the meantime, let's access your account using a private or incognito browser window. This will help us determine if the issue is browser-related. To open one, please use these keyboard shortcuts:
Google Chrome: Ctrl + Shift + N
Mozilla Firefox: Ctrl + Shift + P
Safari: Command + Option + P
Edge: Ctrl + Shift + N
Once you’ve opened a private window, try to log into your QuickBooks Online (QBO) account. If this is successful, I suggest clearing your browser's cache and ensuring that your browser is updated to the latest version.
Also, please ensure that you are using the correct login credentials and website URL to access your QBO accounts.
