Hello guys I have a perfect nginx debian 9 server on my test server The server has ip 192.168.1.100 and I host a domain (domain.com for example) I make a subdomain nas.domain.com and redirect to 192.168.1.101 where I have a nas server. The web interface works fine, but when I test ftp ftp://nas.domain.com , it doesn't work. Only the account made for domain.com goes, I cannot access the accounts and the passwords of the ftp on the nas. How can I make them work? Thx!
