Welcome to the Community, richard.
Intuit generally does not block specific IP addresses. However, there could be security protocols in place or connectivity issues that may trigger such errors.
Since clearing the cache didn’t resolve it and there are no VPNs involved, the situation may require further investigation into the account or security settings. I recommend reaching out to our live support team for immediate assistance.
Here's how you can contact them:
- Go to the Help icon in the upper right corner.
- Select the Search tab and hit Contact Us.
- Click the Ask about something else tab.
- Type in your concern and hit Continue.
- Choose a way to connect with us.
Please take note of their support hours so you'll know when agents are available.
