logging 401 response from mesos

Hi, we faced a problem with synchronization when we enabled authenticate_http_readonly option on mesos-master. After enabling this option on mesos side, synchronization stoped working, but there were no errors on mesos-consul side, even with debug mode. here is tcpdump of session:

healtcheck of mesos-consul shows OK

[root@mesos:~]# curl http://127.0.0.1:31033/health
OK

Is it possible to log such cases? we want to be sure that synchronization between mesos and consul works properly, how we can do it? Thanks in advance
