Since + overrides the non-ff check, this means that the remote side
has receive.denyNonFastForwards (see man git-config) enabled (or a
hook to the same effect).  Deleting and pushing the new branch merely
defeats this refusal because it is no longer a branch *update*.

You should probably check why and by who receive.denyNonFastForwards
was set.  Git itself sets it if you use 'git init --shared', so that
may be one reason.

Note that non-ff updates are generally a bad thing for everyone who
has work based on the affected branch.
