Logging in with the server fails/ keeps refusing my connection

Hello there..
I've been trying to access my server's FTP for 4 days and I still can't connect to it. Any thoughts?

The server uses TLS/SSL explicit encryption.

When I'm trying to connect, nothing happens, it just says "Connection timed out"
Repeating the whole process, still nothing happens. Please help.

Was it ever working?
Can you connect with any other FTPS client?
Did you talk to the server administrator/provider?
