When I try to create an invoice I get an error message. Can't connect to our server?

Good morning, eprivett-. Thanks for joining us here in the Community.

I want to make sure you're able to create and send invoices in your QuickBooks Online account.

As an initial troubleshooting step, I recommend clearing the browser cache. The cache is used to collect frequently used data to make loading web pages quicker and easier. If it becomes too full it can result in certain viewing and performance errors in the system. Clearing the cache will help remove anything that is preventing the connection. Here's how to get this done if you're using Chrome for example:

1. At the top right, click More (three vertical dots).
2. Click More tools and then Clear browsing data.
3. At the top, choose a time range. To delete everything, select All time.
4. Check the boxes next to "Cookies and other site data" and "Cached images and files."
5. Click Clear data.

The following article provides similar steps for other browsers: Clear cache and cookies to fix issues when using QuickBooks Online

Let me know if you're able to create a new invoice after giving this a try. I'll be here if you have any additional questions.
