We have (currently) six Hager Witty Plus charging stations. For a few days I'm monitoring the state of the charging stations, because we had some problems that (randomly) one of them would not charge the car.
I activated trace log for OCPP today and I can see that the charging station, that is marked as not connected with a orange dot, is still receiving and sending messages, like MeterValues. Also conntrack is showing me an established TCP connection on the web-socket.
After restaring evcc the charging station is connected again, displayed by a green dot.
I'm wondering what might cause this issue? Why is evcc thinking it is not connected while communicating with it?
Not sure how you could reproduce that.

Describe the bug
Hello evcc team! Thank you for your work on evcc, it's a great software!
We have (currently) six Hager Witty Plus charging stations. For a few days I'm monitoring the state of the charging stations, because we had some problems that (randomly) one of them would not charge the car.
I activated trace log for OCPP today and I can see that the charging station, that is marked as not connected with a orange dot, is still receiving and sending messages, like MeterValues. Also conntrack is showing me an established TCP connection on the web-socket.
After restaring evcc the charging station is connected again, displayed by a green dot.
I'm wondering what might cause this issue? Why is evcc thinking it is not connected while communicating with it?
Steps to reproduce
Not sure how you could reproduce that.
