Explanation

HTTP 429 'Too Many Requests' on Cisco Expressway is a rate-limiting response triggered when the number of authentication attempts exceeds a configured threshold within a given period. The symptom-authentication failing on more than two devices-indicates the 'maximum authorizations per period' setting is too restrictive. Increasing this value allows more concurrent device authentications before the rate limit kicks in. The other options (credentials refresh interval, rate control period, credentials cleanup interval) affect timing windows for credential caching and cleanup, not the ceiling on simultaneous device authorizations.
