how to pull from the git org repo

[Uwe Brauer]

Hi

I just realized that the org repo I am pulling from is
*   commit 52b09799cfba0a847e93c9e21883266570644245 (HEAD -> master, 
origin/master, origin/HEAD)
|\  Merge: 846801e 21eb69c
| | Author: Nicolas Goaziou <mail@nicolasgoaziou.fr>
| | Date:   Fri May 21 18:30:23 2021 +0200
| |
| |     Merge branch 'maint'

But now 

 git pull 

Gives me:

fatal: unable to access 'https://code.orgmode.org/bzg/org-mode.git/': server 
certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt 
CRLfile: none


Did the repository move, and then where to?

Thanks
