TL:DR: I can't log in to Tildes from Links browser. Other websites are fine.

I'm not the most computer-literate person (especially when it comes to the Internet). I've been getting into Linux and Arch lately, so I'm a little bit better at it now. So I've been trying to learn text browsers (my choice is Links), and although it's been going fine, I can't log in to Tildes. Other websites like Google or Reddit I can log in, but not Tildes for some reason. I enter my username, password, but then it just takes me to the 'we're invite only' page. When I press 'register', it doesn't even lead to register page, it puts me to the 'we're invite only' page again.

I know there's some developers here, do you know what could be the problem?
