Nitter is not working for me either. I've tried multiple instances. The RSS feeds that I've set up using Nitter aren't working either.

Unless this is an unintentional bug, this is a wrap for Nitter and was probably designed to hose Nitter among other things.

Edit: I'm checking the feeds I've set up on my phone and the last tweet is from around 2pm EST, so they basically just hosed Nitter less than an hour ago.

Edit 2: Yewtu.be, a popular Invidious instance, is also down. It's probably a coincidence, but it doesn't bode well either way. Invidious is being threatened too. Mainstream social media are circling the wagons.

Edit 3: If you try to use nitter.cz, you get this message:

Nitter.cz is not working, just like all other Nitter instances. The reason is Twitter blocking all access to it's content without login.

We are sorry, but there is nothing we can do about it right now and we are not sure if the situation will change in the future.

Don't trust corporations, especially those where one egomaniac has all the power. Use open-source and community driven solutions if you can (like Mastodon).

Sincerely, NoLog.cz collective

Looks like this is the end of the line for Nitter.
