Can’t register my PW

Hadn’t used my PW in a very long time. It’s a 3G Gen6. It was jailbroken and had loads of great extras I’d added but for some reason now it’s crippled. I did a reset but now it refuses to be registered, which I need to do to re-break it. Keep getting:
“Unable to Connect - There was an error while registering your Kindle.
Please try again later.”
Anyone have an idea what gives here? THANKS!
