Just a sanity check, what version of Fedora are you using on each
system?  

Do you have sshd running or enabled on the remote server?  Which user
are you attempting to connect as?

Could there be allowed users listed in the sshd_config file?

And while we are at it, check the log files on both systems.  There may
be more info there.  :)

No, as long as you are reasonably sure there was no possibility of a man
in the middle attack on the first connection you should be fine.  If
someone does try such an attack you would be prompted that the keys
don't match and that bad things may be happening.

For the truly paranoid we install the keys manually and disable the
automatic acceptance of new keys.  :)
