I've a server and some proxies (all running Centos 7) and zabbix 5.0.15
The proxies are setup to communicate with encryption using PSK and are working fine most of the time.
Every so often I see this in the server logs for 5-7 minutes and the queue spikes.
2273:20211006:185618.732 failed to accept an incoming connection: from AA.BB.CC.DD: TLS connection has been closed during handshake:
During this period the server loses communication with the proxies that talk over encrypted links and so all the hosts on the proxies then show as offline.
I was wondering if this could be a time sync issue. The zabbix server itself is setup using chrony on the uk time servers. The proxies were setup with ntp, but am considering moving them back to chrony although I don't expect time between these to differ by more than a few seconds.
Any ideas on things to check?
