A user reports being unable to access Google NotebookLM service after switching VPN providers, though they can access Gemini AI through Korean nodes. The user tried multiple dedicated IP nodes in the US, Japan, Singapore, and South Korea, with only the Korean node working properly for Gemini, while NotebookLM remains completely inaccessible. The VPN provider hasn’t responded to inquiries, leading the user to suspect node configuration issues and seek recommendations for other providers. The user verified that their previous VPN allows normal access, confirming the problem likely stems from insufficient node optimization on the new service. This issue involves network access barriers to AI services like Gemini, offering valuable insights for readers interested in Google services, AI applications, and networking technology, reflecting real-world proxy service compatibility challenges.
