Google Tasks Integration – “No OAuth2 implementations available” Error

Hi everyone,

I’m trying to add the Google Tasks integration in Home Assistant, but I’m running into an OAuth error during the setup process.

The error appears when I try to authenticate the integration while adding it through the integrations page.

This is the error showing in the logs:

Logger: homeassistant.components.google_tasks.config_flow
Source: helpers/config_entry_oauth2_flow.py:386

Error message:
“No OAuth2 implementations available: Cannot provide OAuth2 implementation for cloud services. Failed to fetch from account link server.”

This error appears every time I attempt to add or authenticate the Google Tasks integration, and it shows up multiple times in the logs.

Has anyone encountered this issue before or knows what might cause it?
I’m not sure if it’s related to my Google Cloud configuration, Home Assistant Cloud, or something else.

Any help or pointers would be greatly appreciated. Thanks!
