wont open website builder

Hey everyone

I have installed WordPress through my host etc and all is good except when i click my web address link with the ‘wp-admin’ at the end, its my understanding that this should allow me to go to my dashboard and build my site.

I am being told each time that there is problem with the page and it cant find the server. Can anyone help me with this please, its driving me nuts.

I have installed word press through my host that is Crazy Domains. I also purchased my domain name from them at the same time.

Thanks in advance
