A message says I'm unable to login
Carefully read the error message provided by the server for clues to what went wrong. Some things that can prevent you from logging in to a Usenet server are:
Wrong server address
Make sure that the server address or port you've specified is correct.
Incorrect username or password
If your server requires a username and password to log in, make sure you've configured them in Unison, and that they are spelled correctly.
Too many logins
Many servers impose a limit on the number of times you can be logged in to the server at once. If other applications are also accessing your Usenet server account, try closing them.
Server is inaccessible
The server may be down, or there may be a network problem somewhere between your computer and the server. Try again later.
