I updated from version 3.0.9 to 3.2.6
Can not add a new agent.
Old hosts are working at the same time.
The version of the agent and server are the same 3.2.6
Zabbix_get still works, but the interface status is not available
In the server and agent log, even with debug 4 there is nothing about this host
Tried to restart everything does not help

In russian
