drazzy.com certificate expired

FYI #1209 has reoccurred, the TLS certificate on drazzy.com expired 24th December 2025 which causes issues installing via board manager.

In addition to when installing, an error pops up the first time one opens the Arduino IDE and it checks for updates.

Have tried bypassing security and trying to get onto the Drazzy site to see if I could report to somebody but all I get is a blank page and three dots.

Not sure of the relationship between this repository and the Drazzy site, but wondering whether this repository is perhaps a is a fork? If so, then this is perhaps not your issue, but just in case, this is the error message that pop up:

I have temporarily removed the Drazzy URL from my Arduino IDE preferences and added the one from this Github repository instead and for now, the error seems to have has gone away. This is the URL I used:

https://github.com/SpenceKonde/megaTinyCore/blob/master/megaavr/package.json

However, I am not really sure whether this is the URL that I SHOULD be using?
