**Error Code:** 10001 **Error Message:** ANALYTICS_BUFFERING_TIMEOUT_REACHED
In Bitmovin Analytics buffering is measured by two components, based on the player event “buffered” and a heartbeat that is subsequently deployed. ([Read more about it](🔗))
However, when the total duration of the first buffering event and the additional heartbeats last for longer than 2 minutes, we consider this session as timed-out, hence the collector stops data collection, transitions into an error state, and sends out an ANALYTICS_BUFFERING_TIMEOUT_REACHED error.
The error is captured in the web collector from version [2.16.0](🔗), in Android from version [1.18.0](🔗) and iOS from version [1.16.0](🔗)
