The error you've received could be due to a system issue on the RBC's end or data build-up on your browser, Joel.
To assist you accordingly, may I ask where you received the "not available" notification? Is it within QuickBooks or on the RBC Pay & Sync window? Providing us with this detail could help us relay a precise resolution.
If the error was within QuickBooks during the authorization process, I recommend clearing your regular browser's cache. Doing so helps eliminate components that can trigger problems like the one you're experiencing. You can also consider using an alternative browser to narrow down the situation.
On the other hand, if the error appeared in the RBC Pay & Sync window, it's best to contact the RBC Support Team. They can further investigate your inability to integrate QuickBooks with your RBC Pay & Sync system or update you about possible maintenance on their end.
