In the report https://support.zabbix.com/browse/ZBXNEXT-2557 apparently the zabbix-server agrees to send the settings to an outdated zabbix-proxy, aiming to give more time for updating the zabbix-proxy environments.

I have a zabbix-server (6.4.2 - "zabbix-teste.tiozaodolinux.com") and a zabbix-proxy (6.0.17 - "Zabbix Proxy Tiozao" - no Encryption).

In the Menu "Administration->Proxy" it shows:
"Name Mode Encryption Version
Zabbix Proxy Tiozao Active None 6.0.17 - Proxy version is outdated, only data collection and remote execution is available with server version 6.4.2."

Looking at the logs I have:

/var/log/zabbix/zabbix_server.log

  4063:20230427:132230.907 configuration update is disabled for this version of proxy "Zabbix Proxy Tiozao" at "189.115.97.156": proxy and server major versions do not match
   4057:20230427:132230.953 Proxy "Zabbix Proxy Tiozao" version 6.0.17 is outdated, only data collection and remote execution is available with server version 6.4.2.

/var/log/zabbix/zabbix_proxy.log

202255:20230427:132230.916 cannot obtain configuration data from server at "zabbix-teste.tiozaodolinux.com": proxy and server major versions do not match

202266:20230427:132331.031 cannot send heartbeat message to server at "zabbix-teste.tiozaodolinux.com": empty string received

Does this happen to anyone else, or am I doing something wrong?

My settings in this test environment are in the attached prints
