Perhaps this is a silly question, I am a bit of a n00b when it comes to CA´s, but did the GrapheneOS website and services just switch to a different certificate authority or was it always ISRG? (Internet Security Research Group)
Because I blocked some CA´s on a computer for testing, (dont ask me why, lol) I did this a few months ago, but is suddenly no longer connecting to the GrapheneOS website unless I unblock ISRG.
Before I could connect just fine to https://grapheneos.org/ with this certificate being blocked.
Anyway, keep up the good work, I really appreciate the project!
