お世話になっております。

サーバーの情報は以下になります。
CentOS Linux release 8.4.2105
Zabbix 5.0.14
Openssl 1.1.1g

監視対象は以下になります。
Windows Server 2016 Datacenter

新規でZabbixサーバーを構築しているのですが
ZabbixAgentとの暗号化通信を設定するとハンドシェイク失敗のログがzabbix_server.logに出力され続け
数時間に一度しか値が取得出来なくなり、解決策をご教授頂きたく存じます。

Agentとの通信でPSKを使用しなければ値の取得は問題ありませんでした。

ZabbixサーバーがTLS1.3に対応しているのに対し
Windows側がTLS1.2までしかインターネットオプションにて選択できない事が原因かと考えたものの
Zabbix側でTLS1.2のみを使用する設定の特定に至りませんでした。

状況としては以下の
One side connects with PSK but other side uses OpenSSL with PSK support disabled
が近いのではないかと考えられます。
