PMM targets lost after some time

We have setup PMM server (latest docker image v2.25) ,Around a few days after all monitored hosts have been added to the server,we observe some targets becoming lost. in Inventory/Nodes we can found the nodes, but can not find in OS/Nodes Overview。
with tcpdump can detect the target’s messages have been received 。

only after restart pmm server ,the lost targets appear now。
