I just received my FireBeetle 2 ESP32-E boards today, that I want to use for some sensor R&D.

I followed the steps of the wiki one by one.
I added the json download link in the preferences.
But I have an error downloading message when I want to update the board library.

When I check the json url on the isitdownrightnow website, I got a 404 error.
Is there a problem with the download link?
Is there an alternative link?

I'm working on a linux (kubuntu 20.04) computer.

Can you help me out?

Tnx in advance.
