Three other ways to use Gemini
1. Access the Gemini API in the Google Cloud Platform Console.
2. Use Google AI's Gemini chatbot.
3. Use third-party applications or tools, such as Bard.
If the official website address has no permission, you can switch networks again and then log in through Bard. The moderator relatively recommends using Bard. It seems that official website login is stricter about blocking IDs; after using Bard, you can enter easily. https://bard.google.com/
