I/O Errors

[Febus123]

Hi, my ebusd runs fine for like a couple of hours between a Vaillant heating and home assistant with MQTT, Mosquito and ebusd add-on. Then all over sudden I receive generic IO errors and no further connection is possible.
Any hints or suggestions?

Some additional info:

Heating is a Vaillant ecoTec. ebusd connect to network via WiFi.
