[tor-relays] keypair issue after backing up relay

[Matlink]

Hi,
I'm running a tor relay. I once had some trouble about running it, and I
decided to reinstall tor via apt-get. Of course, it did erased all my
private and public keys, that I missed to backup before reinstalling tor.
Then I ran tor again, with the new identity. As I have a container
backup running every day, I was able to recover the erased private and
public keys, that I put them back.
I can run tor with my original identity, but the directory server is
saying me '[WARN] http status 400 ("Looks like your keypair does not
match its older value.")'.
How can I fix it ? I would like to keep the original identity, since I
had all the convenient flags and don't want to wait another couple of
weeks to get them back with a new identity.
Sincerly,
