How long it takes to index all the backlinks?

I dont want to post my web to get a nofollow.
but in here at domainstats . io / recetasymanualidades . es my wife´s 2 month old web is doing not so good.
I have problems with majestic, I cannot make it read the site, giving me a robots.txt error even tho I know there is no problem with robots.txt because I even used the same that I got in my web.

appreciate all the suggestions on what I am doing wrong.
