I didn't supply an email, but I waited 30 minutes, as well as try to resolve it by password manager; however it didn't work. Anyone got any suggestions?
Sorry you're having trouble accessing your nation. Unfortunately, there are only two acceptable proofs of ownership of a nation: the password and the recovery email using the Forgot your password link. If you forgot the password; and either didn't set or don't have access to the recovery email; that nation is lost to you.
However, the password manager may have the wrong password saved. I would recommend trying to type the password in manually.
Please submit a GHR if you have further questions.
