Welcome to QuickBooks Community. I'll lay down a couple of solutions to help you fix the linking issue.
It's possible that the system wasn't able to detect the credentials you used. We need to make sure we log in using the same email or user ID.
Also, it'd be best if you'll use the company’s QuickBooks Time web address to ensure that you'll sign in to the right account.
If the error continues, you'll want to perform some basic troubleshooting steps to see if this error is due to the accumulated temporary internet files. First, use an incognito window and check from there if everything's fine.
Please reach out to our Support Team if this error persists so they can conduct further investigation. From your QuickBooks Time account, select the Find answers and get help icon, then tap Chat Now.
