upgrade from 20241027 to latest 20250615 firmware breaks arbitration
i recently upgrade the firmwae to latest after some whle i got greeted with arbitration/connection errors like: [bus error] send to fe: ERR: arbitration lost, retry [bus notice] arbitration won in invalid state receive response [bus notice] arbitration won in invalid state receive response [bus notice] arbitration won in invalid state receive response sometimes the connection would work/ reading values was possible, after some time the ebus connection was lost.
in this times my vaillant arotherm plus was also behaving strangely ( using electic heater/ throwing error about connectio issues)
after reverting back to 20241027 everything works (like it did for ~ 2 Years)
if you tell me where and howto capture usefull debug logs I'll be happy to provide those.

It works for me again. Apparently I made a mistake here: Network adapter address 192.168.178.79:9999
but it must be -> enh:192.168.178.79:9999
