EM24 Ethernet regularly loses network connection

I have the EM24-E1-AV2 X version with LAN connection and the latest firmware X-1.1. Unfortunately, the meter loses the network connection every few days/weeks so that my ESS system (RaspberryPi 4 with Venus OS 2.89) has no data and switches off.
I have tested the EM24 with and without DHCP, both make no difference. There is a Fritz box in between and the data from the EM24 is only queried by the Venus ESS.

If the connection is lost, I have to deactivate and reactivate DHCP manually on the EM24, then it works immediately. Unfortunately only for a short time until the next failure.

Does anyone have a solution?

Network/DHCP errors, particularly if they are random, are often difficult to pin down. I think the first thing I would do is try a different router to narrow down the possibilities?
