We just got a new CF 10 VPS with Hostek. All seems well but in cfadmin we keep on kicked back to the login screen. I know that you can't have more than one user logged in at a time but even with just one user, it keeps on kicking us out. We're not doing any particular action (ex. posting a form) when this occurs. It seems to be randomly occurring after a few clicks here and there. In the blog I linked to, some in the comments were having this problem too but there isn't a solution posted.

A couple of possibilities.

  • As other have suggested you might be having trouble with cookies. But if this were the case I would sort of expect that you would not be able to log in at all.
  • Your assumption that only 1 login at a time is a possibility. Check the server admin logs to see if that is true.
  • Your Cf server might be restarting. A restart would kill your session causing you to have to login again. Check the event logs, the out logs and the runtime/bin directory (where you will see hot spot errors).
  • Your default session timeout might be set to draconian levels. The default is typically 20 minutes, but if someone has changed it to (for example) 2 minutes you would get logged out any time you took too long to click on something.

That's all I can think of :)

Thanks for the useful suggestions, unfortunately nothing helped. I'm sure it's only one user logged in at a time – CutOffTies Aug 28 '12 at 20:29

For us the problem goes away when we access ColdFusion administrator using a numeric IP address (eg instead of
