I put the RocketChat, it's OK.
I make a config for nginx (on the other server), for Http, everything is okay, works.
Made a config for SSL (by manual, or rather a copy of paste, from the dock RC), not that does not work, and sends to another server, with a different IP
RocketChat - 1.104:3000
WEB - 1.41
Other 1.43
Why is this happening?
