Fixed Check-In Failures When an Agent Update Was Pending - Agents connected to a self-hosted LoadGen Platform logged Platform check-in failed on every check-in cycle whenever the Platform had an agent update waiting, because a timestamp in the check-in response was not read correctly. The failure stopped the rest of the response from being processed, so pending agent updates were never applied and measurements were cached locally instead of being sent. Check-ins now read the timestamp correctly and continue normally.
