Unable to install MariaDB on new VPS, looks like the IP is blacklisted from previous use or filtering

We are trying to setup a WebHosting service and are unable to pull mariadb-server since we get the following errors around mariadb. From previous support requests recently I assume this is due to our IP being blacklisted from previous use.

E: Failed to fetch https://dlm.mariadb.com/repo/mariadb-server/11.4/repo/ubuntu/dists/noble/InRelease 403 Forbidden [IP: 2607:f8b0:4001:c01::cf 443]
E: The repository 'https://dlm.mariadb.com/repo/mariadb-server/11.4/repo/ubuntu noble InRelease' is no longer signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
