ABB Terra Charger loses connection

[h5r9]

Hello,

Got the charger working today with the HA OCPP integration (using IP address instead of homeassistant.local hostname).

However, it loses connectivity - has done this now 3 times already - after losing 2-3 pings, the server closes connection (see the log below). And usually (2 cases from 3) Terra does not initiate it again, unless restarted.

I would really appreciate some advice here..
