Arduino 2.3.3 Not accepting Digispark

[Goldenshuttle]

I searched topic on this forum but the solutions I found here did not work. All I need to is have digispark(USB digistump) added. I saw 2 methods, the old one from preferences adding the .json link which did not work. second one is download a zip file, unzip and run one of the files inside. Both did not work. windows 10 on i5-6300 core. please help. This took so much time.
once I add the json link and press ok, ok, you get a message saying server refused the connection

Hi @Goldenshuttle. The recommended way to add support to Arduino IDE for Digispark boards is by installing the ATTinyCore boards platform.

Unfortunately there is currently a problem with the website of the creator of that platform (SpenceKonde/DrAzzy), which causes the Boards Manager installation of ATTinyCore to fail:

https://drazzy.com/package_drazzy.com_index.json - SSL-certificate expired 3 days ago

As a workaround, I have published a provisional Boards Manager URL that will allow the Arduino community to easily install this platform until such time as SpenceKonde/DrAzzy can get the problem with the website fixed.

I'll provide instructions you can follow to install ATTinyCore:

1. Select File > Preferences... (or Arduino IDE > Settings... for macOS users) from the Arduino IDE menus.
   The "Preferences" dialog will open.
2. Enter the following URL into the "Additional Boards Manager URLs" field in the "Preferences" dialog:

   https://raw.githubusercontent.com/per1234/ReleaseScripts/refs/heads/provisional-package-index/package_drazzy.com_index.json
   

   If there are already Boards Manager URLs in the field, separate them with commas.
3. Click the "OK" button.
   The "Preferences" dialog will close.
4. You will now see a "Downloading index: ..." notification at the bottom right corner of the IDE window. Wait for that notification to close.
5. Select Tools > Board > Boards Manager... from the Arduino IDE menus to open the "Boards Manager" view in the left side panel.
6. Scroll down through the list of boards platforms until you see the "ATTinyCore" entry.
7. Click the "INSTALL" button at the bottom of the entry.
8. Wait for the installation process to finish, as indicated by a notification at the bottom right corner of the Arduino IDE window:

   Successfully installed platform ...

You should now see the boards of the installed platform under the Tools > Board menu in Arduino IDE.

There is information about ATTinyCore's support for the Digispark board here:

Please note that the Boards Manager URL I provided in step (2) of the instructions above is only intended to be used as a temporary workaround for the problem with the official Boards Manager URL for ATTinyCore.

You should monitor the bug report at https://drazzy.com/package_drazzy.com_index.json - SSL-certificate expired 3 days ago · Issue #885 · SpenceKonde/ATTinyCore · GitHub and once SpenceKonde reports that the problem is fixed, change the URL in your Arduino IDE preferences to the official URL, which is specified in the ATTinyCore documentation:
