Why is ftp not working?

Question

FTP

I took a simple order for the VP, according to the technical specification, I just had to slightly fix the theme and that’s it, but when they gave access, it turned out that the theme was assembled on the most complete constructor and it was impossible to add half of the technical specification from the admin panel (there is no button to edit the theme), so I asked for FTP access , gives me a login, password, I go in, and there is generally something not related to the VP, then I realized that this is an old site. He asked if the domain is a host, he sends some domain, I connect, and there is the same picture, and the domain of the site that opens is completely different. Question: How can files from another site be opened from the domain of one site?

Answer 1

It turned out that FTP was broken, they sent me a new working access

Answer 2

The answer to the question. Domains are tied to ip addresses. Check if ips are given correctly
Try to go not by domain, but by ip
Well, maybe there is a balancer there
Or a bunch of this log / pass for ftp has a specific assigned folder
