Error 504 when trying to renew my service

Hello :slightly_smiling_face:
A few days ago my service just arrived to expiration.
I forgot to renew it before (Yes, I'm totally dumb). Now that my service is expired, I want to renew it but when I confirm the second step, I'm redirected to this page: https://eu.ovh.com/cgi-bin/order/renew.cgi that doesn't seem to be working

If I can't renew it in the next ten days, my service will be deleted, the machine contains very important data for me, I can't risk this happening :frowning:
