hostname and rDNS issues

hello, this is my first post.
I already configured cwp many times with no issues. This time I have a weird error on a freshly installed server.

Your Hostname is: xxx.mydomain.tld and it resolves to IP: (ERROR: You don't have a valid hostname set!)
rDNS/PTR = FAILED, check with your hosting provider! FAILED

i have no idea why I'm getting this. if I go to list my zones it seems everything fine.
When I configured my server I had my FQDN set correctly, changed my network configuration to a static ip... just like I always did on many other installations. in my domain provider the name servers are customized to my ip...
what can be wrong?

Thanks in advance

did you added hostname/subdomain DNS A record ?

did you added hostname/subdomain DNS A record ?

in cwp or in my provider panel? I did in my provider panel... never done in cwp

ok the post can be closed. It was my domain provider that still hadn't propagated the dns for a small issue of them. it's all regular now. thanks
