I live in Indonesia, and I don't find any recent news that mention X (formerly Twittwr) and or Discord being blocked by the government. The only relevant news from a quick Google search I can find is about the government threatened to block X due to pornography content in 2024.
You can even check for yourself if a domain is blocked by visiting https://trustpositif.komdigi.go.id/.
Also for your unability to access the VPN, as far as my experience goes, in the past some providers do block access to VPN. But, I am not experiencing that for at least the last 5 years.
So, maybe you can try changing your internet provider and see if you can connect to VPN?
