Error when trying to link account with txadmin

I am following this: How to Make a FiveM Server in 2023! (UPDATED) | FREE - YouTube tutorial

Every time I open FXSever and it redirects me to the txAdmin Login website, I enter the (correct) pin and press link account. This then results in a redirect to a page looking like this

I’ve never tried anything like this before, I’m not sure if this is a try again in an hour thing or if I’;ve done something wrong. Could anyone help?

Same error for me too
