wp-admin - ERR_EMPTY_RESPONSE

Question

When I try to access my wp-admin I'm getting on some specific sites ERR_EMPTY_RESPONSE.

This includes - plugins, themes, general settings and more. Some areas are still accessible, like Pages or Posts.

I tried basically everything. I renamed the plugins folder and themes folder, it didn't work. Then I removed the whole WP install (I kept wp-content, it contains a lot of stuff), and reinstalled everything (wp-admin, wp-includes etc). And it still didn't work. I changed all permissions to 755 with chmod -R 755 ... and still no effect.

The thing is - it was totally random. I actually didn't install anything or change anything in the last week. I suspect that it is a problem with my host, AWS. It might be firewall settings or something like that?

I'm completely lost and a hint or some kind of help would be greatly appreciated.
