577577### Authentication loop with SSO and corporate proxies
578578
579If browser tabs spawn repeatedly when using AWS SSO, remove the `awsAuthRefresh` setting from your [settings file](/docs/en/settings). This can occur when corporate VPNs or TLS inspection proxies interrupt the SSO browser flow. Claude Code treats the interrupted connection as an authentication failure, re-runs `awsAuthRefresh`, and loops indefinitely.
579If browser sign-in tabs keep opening when you use AWS SSO, remove the `awsAuthRefresh` setting from your [settings file](/docs/en/settings).

581The loop can occur when corporate VPNs or TLS inspection proxies interrupt the SSO browser flow. Claude Code treats the interrupted connection as an authentication failure. When a later request finds the credentials still expired, Claude Code re-runs `awsAuthRefresh`, which opens another tab.

581583If your network environment interferes with automatic browser-based SSO flows, use `aws sso login` manually before starting Claude Code instead of relying on `awsAuthRefresh`.
