SMF on Ionos Cloud--admin access?

[Tapioca]

I have an Ionos cloud account that came with SMF pre-installed.

Ionos gave me the IP for the SMF instance and I can access the forum landing page via IP or the domain name I've associated with it.  They also gave me
admin area: http://[IP]/index.php
user: [uname]
password: [password]

When I go to IP/index.php, that username/password does not work so I'm thinking there must be some other way to access the admin controls so that I can develop my new forum.

I have SSH root access to the server if I need to do it that way.  I just need a little guidance.

I tried Ionos support and they knew nothing about it.

I'm new to this so please let me know if I've left out essential information.

Host installers are not recommended.  You can do a clean installation yourself, it's easy.

Also, there is no separate admin login...you log in to the forum, if your account has admin access, then you have access to the admin menu and functions

Point Ionos support to https://www.ionos.com/cloud/cloud-apps/simple-machines-forum and they will figure it out.
