 banned for 600 seconds

Hi everyone, does anyone know the cause and how to deal with it?

After a week of observation, I discovered a problem. After a while, p2pool will disable the front-end xmrig-proxy for 10 minutes. What is the reason for this? After being disabled for 10 minutes, it will return to normal.

p2pool log:
WARNING 2023-11-17 09:09:25.3223 P2Pool submit_block (external blob): daemon returned error: Block not accepted
**WARNING 2023-11-17 09:09:56.3888 StratumServer peer MY_XMRIG_PROXY_IP_ADDRESS:50564 banned for 600 seconds**

**When p2pool disables xmrig-proxy, a large number of the following logs appear in the xmrig-proxy log:**
