[BUG] haproxy + saltstack salt '*' test.ping minions(random) not connected

[iostrovskii1976]

Description
In the haproxy + saltstack configuration, some minions (randomly) do not respond the first time with salt ‘’ test.ping, they give out no connection, when repeated, all minions respond. It has been empirically established that when the minions are idle for more than 15 minutes, this behavior manifests itself. If you run salt ‘’ test.ping every 12-15 minutes, then everything works well.
Salt version 3006.9/3007

timeout server and timeout client for the publish port should be equal to the master's publish_session which defaults to 86400 seconds. This is a known issue in our documentation.
