Today I go to the panel to create an FTP account using the port defined by me 7123 and it does not work. It shows the error: "ERR_CONNECTION_REFUSED". I enter the SSH console, log in as ROOT and type the command service bt start - nothing happens. Same: service bt stop, service bt restart. When I enter just bt, the panel configuration menu does not appear. When I type bt 16, port 7123 appears. The one I'm using. What may be the problem? Websites, MySQL databases, SSL certificates and FTP server are working fine.
