Error 81 how to fix it

I can help you in resolving the error you've encountered, @usermariajesusbanet.

Can you tell us more about where did you receive this error message? That'll help us get the best resolution for the error you're having.

It's possible that a piled-up cache in your regular browser caused this error message. You can clear your current browser’s cache to resolve this. 

But first, try using a private browser or an incognito window when trying to reconcile your account. If you no longer have the error, then you can clear the cache in the one that you're currently using if it works. Here’s how:

• For Chrome, press Ctrl + Shift + N.
• For Microsoft Edge or Firefox, press Ctrl + Shift + P.
• For Safari, hold down Command + Shift + N.

If it works, here's how to clear cache and cookies to fix issues when using QuickBooks Online. Restart your browser right after. You can also try to reconcile your accounts using other supported browsers (Firefox, Google Chrome, Safari, Microsoft Edge) if the steps above didn’t work.

Stay in touch if you need further assistance in resolving the error you've encountered. I’m always glad to help in any way I can. Take care and have a great rest of the day!
