Error while using forecast.solar (free version)

While using forecast.solar by selecting it in the configuration of EMHASS I get the following error.
Running latest version, but also happens on v0.8.6

Hi,
I've just tested everything and unfortunately I'm not able to reproduce your error.
I tested our three methods, they are working perfectly well.
I've coded a small script to test all PV forecast methods at once.
You can test it yourself if you want to check that you are able to retrieve all forecasts.
The script is here: https://github.com/davidusb-geek/emhass/blob/master/scripts/script_debug_forecasts.py
To do this clone the EMHASS repo and launch the script.
You will need to define the needed variables for solar.forecast and solcast methods in a secrets.yaml file.
Here is the output of the script for my case, with no errors whatsoever:
So your problem is elsewhere.
Probably an API number of calls limitation?
Hi, yes it seems to be the API call, I tested it. First 2 calls ok then I got the error again. 5 min MPC calls.
