I have installed Centreon version 25.10.9 on a Red Hat 8 operating system. I am using the open-source edition. The server IP is 192.168.1.100. I added a poller with the IP 192.168.1.101. This poller encountered a failure, so I completely reinstalled it on a virtual machine, keeping the IP address the same as 192.168.1.101. The OS is still Red Hat 8. I successfully registered the poller to the server, but when I check the web interface under Configuration > Pollers, it shows that this poller is not running.
The poller's log file at /var/log/centreon-gorgone/gorgoned.log contains the following errors:
```

```
Does this mean that there are original poller-related configurations left on the server side? How can I configure it so that the new poller can be properly registered to the server?
