    a detection timeout. However, we found this caused frequent telemetry and traffic failures during slow connections, while increasing latency
    for misconfigured server first protocols rather than failing fast.

    This timeout has been disabled by default. This has the following impacts:

    - Non "server first" protocols will no longer have a risk of telemetry or traffic failures during slow connections
