What should I do if I try to connect the server in FileZilla to upload mods there, but it is constantly written, the connection is established, waiting for an invitation?

Question

FileZilla

I’ve been sitting for 30 minutes now, trying to understand why it doesn’t work, I double-checked everything, the password, host, username, everything is correct, but it says: Connection established, waiting for an invitation ...
Unable to connect to the server.
