Zabbix proxy -> server: TLS read set result code to 5

[kovax]

Hi,
I have a problem with the connection between the Zabbix proxies and the Zabbix Server. I'm not sure, if it's a bug, maybe you saw something like this previously..

The setup is the following: 2 Active Proxies connecting to the Server. There's TLS with PSK set up between the proxies and the server.
Proxy version: 3.4.11 rev 82160 (400 vps per proxy for 36k items, 25% CPU utilization with 4 cores)
Server version: 3.4.11 rev 82160

Every 1-2 day, the server loses the proxies for 5-6 minutes, in the proxy log, I see the following message:

cannot send proxy data to server at "XXX": TLS read set result code to 5:
SSL_Shutdown() with XXX set result code to 5:

Is it possible, that this is SSL/TLS related? Can I somehow tweak the SSL timers? I can't see any network related problem.

Thanks
