The site is a Vue app deployed by gitlab. It was showing correctly a couple hours before the last push in custom domain. I set the name servers and dns earlier and netlify tells me everything with them is in netlify.
PD; I had to make a workaround in my own server loading a dist folder in repository and pointing the domain to this folder bc client have an event tomorrow and the need to publish inmediatly, but otherwise netlify still showing old site. Thanks in advance
