Cannot put SSL on my domain

Basically I purchased the hosting 4 hours ago, and at the start on the domain SSL was enabled, I was doing some quick tests and disabled SSL at that domain.

After 1 hour the SSL task was still running on ongoing tasks and in a bit of time it removed itself, but now I cannot put SSL into the domain because of this errors im getting;

An error has occurred modifying the domain/s of your hosting plan.

You have added multisite hosting within the last two hours. Please note that they may not be included in your SSL certificate.
You can order free certificates or import certificates that you have purchased elsewhere, but an error is preventing you from ordering paid certificates: Impossible to modify this attached-domain.

Someone able to help me? Thank you.
