I upgraded the Zabbix server to version 7.0, my web monitoring only collects data when I restart the server. After a while, it stops retrieving data, while all other monitoring items are working normally. Can anyone help me troubleshoot this? There's nothing related in the logs, and the web interface shows no errors either.

It's like the web monitoring is in a semi-dead state. Today, there was only data for 3 hours, and when data was being collected, I could see the connections in netstat. Is this a bug in version 7.0?
