We have found that some ad blocking applications and DNS filters are blocking access to GeForce NOW, and resulting in a connection/login failure as seen in the below screenshot. We are working with some app developers to fix this.
In the meantime you can try to work around this problem by trying these steps:
- Disable any ad block software running on your phone when trying to login to GeForce NOW
- Disable the Private DNS setting on your Android phone. This is under Settings > Network & internet > Advanced > Private DNS > Off.
If you have tried these and still have errors, please contact NVIDIA Customer Care.
