Website not working after NS change

I changed the nameservers towards those of Cloudflare on 20/10/2022 but from the few weeksI cannot reach the website anymore. I’ve added all the DNS records that should be relevant. The message from Cloudflare itself is:

Domain transfer complete!
Your transfer is complete, however Cloudflare may still be ensuring your nameservers are correct. If you see nameserver instructions below, then you can safely ignore them.

The hosting company says that the NS points to those of Cloudflare, and I’m at a loss at what I did wrong to make it go through Cloudflare…and be able to be reached again. I need help with the setup.
