Hi @csiknor, thanks for reaching out and my apologies for the delayed response here.
I understand the confusion; you're running into a somewhat confusing error message. I'll raise it with the team to make sure this message gets improved, but in the meantime, it's good to know that this occurs when the 1Password app has trouble signing in with the 1Password servers.
Do you see the "1Password is offline" banner in the 1Password app? If so, make sure you have an active internet connection and try clicking "Reconnect".
Let me know if that helps, if not, we'll discuss the next steps.
