Hello,
We are experiencing some odd errors between our 5.4.0 Zabbix servers and two agents on our LAN. This *seems* to have started after the latest round of MS patches, but I cannot prove a correlation.
Here is a snippet of the agent log:
10184:20210729:083747.976 Starting Zabbix Agent [CCNWO-HOST-02]. Zabbix 5.4.3 (revision 68dc2b05cb).

The dashboard shows these as a "Zabbix Agent is not available" alert.
Any ideas as to what might be causing this?
Thanks.
