Hello,
I have upgraded zabbix proxy and agentd to 7.0.19 version, server is 7.0.8 version. I monitor windows with proxy group, whenever I add log monitoring item active checks become not available immediately and zbx icon become orange also can't monitor active items. I have checked firewall and network and it seems there is no problem. Is there any solution or what should I check?
zabbix_agentd.log:
2025/10/30 17:03:45.006904 cannot connect to [10.**.**.**:10051]: read tcp 192.**.**.**:52635->10.**.**.**:10051: i/o timeout

Thanks in advance for any ideas or guidance you can provide
