Server doesn't recognize me as owner!!! Or admin!!!!

I just got my server up after weeks of working with it. But now the user text file isn’t recognizing me as a super admin or owner. what can i do to fix this? I’ve used my differen’t steam ids and still nothing i triple checked my steam number and everything. ass mod wont even work for me. I need some help with this issue

On Assmod did you try doing rcon_password (your password) and then rcon ass_giveownership x (x being the number in FRONT of your name when you type “status” into console)?
