Hi @DenisL
please read
We will be beginning brown-outs for new ACME v1 registrations for the production environment for the following dates of this year:
- October 10th to October 11th
- October 16th to October 18th
- October 31st onward
We will be permanently disabling new ACME v1 registrations in the production environment on October 31st .
So you can wait one day. But you should update your client. In three months, new registrations aren't possible.
