I ran into many troubles when I first encountered hive signer
Here are tips from what I've learned
- USE ACTIVE KEY when importing the account
Hive signer for some reason allows you
To enter different keys but only the active key is really required.You will only be notified after a mistake. Just remove the account you imported and re import it this time using active keys. - Import keys in sign authorities
This is stated in the docs section of hive signer though it took me some time to find it
It gave me the "page not found error" before I made this step
