Solis integration stopped working after HA update

[pettemp]

Hello,
Updated my Home assistant and now my solis integration is not working anymore. I'm not sure, which update did this, but now i'm running HA ver 2025.11.1 and still not working. I took away integartion and tried to make it again, same way as before (worked fine several years) but now I get every time "failed to set up: check the logs".
When I check logs, I found there every time this:

Logger: homeassistant.config_entries
Source: config_entries.py:761
First occurred: 14:52:56 (1 occurrence)
Last logged: 14:52:56

Error setting up entry Station 12691B for solis
Traceback (most recent call last):
File "/usr/src/homeassistant/homeassistant/config_entries.py", line 761, in __async_setup_with_context

hass.config_entries.async_forward_entry_setup(entry, "sensor")

AttributeError: 'ConfigEntries' object has no attribute 'async_forward_entry_setup'. Did you mean: 'async_forward_entry_setups'?

Any help? What is wrong?
Thanks.
