Urgent: WP Domain Connection & FTP Access

I need a webmaster for a small, urgent task. I have a domain, hosting on OVH, and a WordPress subscription. The domain is connected to OVH and my DNS is configured. Now, I need help with: - Connecting my "Work In Progress" WordPress page to my domain. - Accessing files hosted on my FTP. I'm able to upload but can't access them via a browser. Currently, any URL pointing to my file redirects to the OVH "Site under construction" page. The types of files I'm trying to access are various document types. I would appreciate your prompt assistance, as this is quite urgent. I look forward to your help. Thank you.
