OAUTH_NETWORK_ERROR

Issue

Glean could not establish a network connection to the identity provider's token endpoint. This can be caused by DNS resolution failures, firewall rules blocking outbound traffic, proxy misconfiguration, or the provider being temporarily unreachable.

Resolution

1. Wait a few minutes and retry the OAuth flow from the Glean Admin Console.
2. Verify that the token endpoint URL configured in Glean is correct and reachable.
3. Check that firewall rules and network policies allow outbound connections from Glean to the identity provider.
4. For on-premise or private network deployments, confirm that proxy settings are correctly configured to allow traffic to the provider's OAuth endpoints.
