I have some problems to connect my payopal account to quickbooks, password and user are correct

Let's make sure to use the right PayPal link to connect the account successfully, user13059. 

We can do this by logging in directly to the PayPal site (Outside QuickBooks). From there, copy Paypal's URL then follow the instructions below:

1. In QuickBooks, go Banking > Banking. 
2. Select the Add account tab. 
3. Paste the URL you've copy on the search field. 
4. Enter your login credentials and follow succeeding instructions.   

If this wont work, I'd recommend contacting our support team. They'll be able to run some investigations to help you identify the issue further. 

Here's how you can reach out to them:

1. Click Help at the top. 
2. Select Contact us. 
3. Enter your concern about unable to connect to PayPal. 
4. Hit Let's talk. 
5. Select Get a callback. 

Make yourself comfortable of visiting us again if you need anything.
