Anyone experience with connecting a Growatt solar-inverter?

Sorry for crossposting.

I’ve been using the Growatt integration a while now, and it has been working great.
However, since yesterday evening something has changed and today no data has been received.
It’s all there on the dashboard hosted by Growatt, so the inverter and datalogging is working as before, it’s just that HA no longer gets any data.
I removed and re-added the integration to make sure I am using the most recent one.

Error while setting up growatt_server platform for sensor
Traceback (most recent call last):
  File "/usr/src/homeassistant/homeassistant/helpers/entity_platform.py", line 249, in _async_setup_platform
    await asyncio.shield(task)

Etc.
Anyone else have this issue?
