Hello folks,
have a questions. I', trying to login to my growatt, but get following error by running mix_example.py. Any idea? I read the forum with having the newTwoLoginAPI issue, but it looks like it's already using this. But unfortunatelly it's still not working.

Do you know if i have to activate my account to be aple to use the api?

debian@debian11:~/growatt2/PyPi_GrowattServer/examples$ python3 mix_example.py

Growatt recently began blocking certain user-agents. It seems they don't want us to use this API. That's probably what you're experiencing.
