Copilot++ not woking. suggestions doesn't appear

Copilot++ doesn’t work.
I have disable, and enable. Restart cursos, unistalleit and install it again.
Yestarday night was working well but this morning doesn’t work.

I am using free version.

In the status bar at the bottom of the cursos the icon of ‘copilot++’ shows a message saying " Requires pro ( custom model) ".

in the OUTPUT of terminal of Copilot++:

[info] CURSOR LOG: Finished creating provider!

Also the codebase indexing is always in loading mode.

can this be the reason of not having working copilot++?
copilot++ is not free?
do I have to upgrade to Pro to use copilot++?

Free 2000 completions, in pro unlimited

Thank you!
