Hi, @120Romances. I'm happy to help you out with this. I just have a few questions to make sure I'm giving you accurate advice going forward.
When do you see this error message appear? Is it right after you try to log in?
When did you first start seeing this?
Have you tried to log in to your store using any other devices, browsers, or internet connections?
I can try to troubleshoot this with you further once I have more information. That being said, I'd also recommend speaking with our support team through the Help Centre here for help with this. We can't see any account information here over the Shopify Community, but if you speak with us through the page I shared we would be able to review this with you in more detail. When you visit that page, please type your question or problem to the Help Center assistant so it can direct you to support from there. If you're not seeing the option you need, you should be able to find more options at the bottom of the chat box.
Please let me know if you have any questions in the meantime!
