What causes "session validation failed: %w" in AlexxIT/go2rtc?

Verify Ring credentials (email/password or refresh token) supplied to the client are correct and current

session validation failed

Error message

session validation failed: %w

What it means

RingApi.Request wraps any error from ensureSession() with 'session validation failed'. The library maintains a Ring session (auth token) and validates/refreshes it before every API call; if that validation or refresh fails, the request is aborted before being sent. This means the Ring credentials or session state are unusable.

Solutions

Verify Ring credentials (email/password or refresh token) supplied to the client are correct and current
Re-authenticate from scratch: clear cached session/token state and log in again to obtain a fresh session
Check network connectivity to Ring's auth/API endpoints (proxy, firewall, DNS)
If 2FA is enabled on the account, supply the required verification code/token as the library expects
Check that the system clock is accurate (large skew breaks token validity)

Example fix

// before
ticket, err := c.ensureSession()
if err != nil {
    return nil, fmt.Errorf("session validation failed: %w", err) // opaque to caller
}
// after
ticket, err := c.ensureSession()
if err != nil {
    if errors.Is(err, ErrInvalidCredentials) {
        return nil, fmt.Errorf("ring login rejected credentials, re-authenticate: %w", err)
    }
    return nil, fmt.Errorf("session validation failed: %w", err)
}

Defensive patterns

Strategy: try-catch

Validate before calling

// Go: check session state before calling
if err := api.Ping(ctx); err != nil {
    // force re-login before real calls
    if reauthErr := api.Reauthenticate(); reauthErr != nil {
        return fmt.Errorf("cannot establish ring session: %w", reauthErr)
    }
}

Try / catch

// Go
resp, err := api.Request("GET", url, nil)
if err != nil {
    if strings.Contains(err.Error(), "session validation failed") {
        // re-authenticate then retry once
        if rErr := api.Reauthenticate(); rErr == nil {
            resp, err = api.Request("GET", url, nil)
        }
    }
    if err != nil {
        return err
    }
}

Prevention

Refresh credentials/session proactively before expiry instead of relying on lazy validation
Use a refresh token rather than password-based login where the library supports it
Monitor NTP/clock sync on hosts using the client
Handle 2FA requirements at initial login, not mid-request

When it happens

Trigger: Calling RingApi.Request (any method/URL) when ensureSession() fails: no session exists and initial login fails, the stored session/token is expired and refresh fails, or invalid credentials were supplied to the client.

Common situations: Wrong or revoked Ring username/password or refresh token; Ring changed its auth API; network outage or firewall blocking Ring auth endpoints; 2FA/verification code required but not provided; system clock skew invalidating tokens.
