Issue with Modbus Integration and Resolution

I've been successfully using the Modbus integration for quite some time (with excellent results 😊). However, yesterday around 3:00 PM, the integration suddenly stopped working entirely. I hadn't been at home and didn't make any configuration changes in Home Assistant.

After spending several hours trying various solutions — unplugging, resetting, setting a static IP, reconfiguring, and so on — I reapplied the latest version of the .yaml configuration from this repository. To my surprise, it started working flawlessly again.

It's worth noting that during the troubleshooting process, I was unable to ping the inverter or locate its DHCP-assigned IP address in my LAN or ARP table.
