BINUSMAYA Praktikum is finally fine.

A few days ago Reinhart wrote a news saying that the site was inaccessible in iOS and macOS since they are using an older, Let's Encrypt certificate which was expired at the end of September.

And today, I just wanna say that the site today works as usual, as the site now uses the newer certificate based on ISRG Root X1!

They replaced the certificate 3 days after he posted it, see also https://www.ssllabs.com/ssltest/analyze.html?d=bluejack.binus.ac.id

If you're the one spreading the issue to your lab assistants, we just wanna to say thanks!
