Describe the bug
Since latest update (2.9.10), some previous certbot implementation has been broken :
'Namespace' object has no attribute 'dns_ovh_credentials'
Indeed, the field in the letsencrypt/renewal/npm-2.conf (in my case there is a "-2" suffix) has no prefix and is now called "credentials" instead of "dns_ovh_credentials".
A manual updates solves this issue.

Nginx Proxy Manager Version
2.9.10

To Reproduce
Steps to reproduce the behavior:

Have a previous certificate (I saw the problem with ovh) with a previous version of NPM.
The line in the certificate renewal should be something like :
dns_ovh_credentials = /etc/letsencrypt/credentials/credentials-2
Update the version of NPM
Certbot renewal should fail with 'Namespace' object has no attribute 'dns_ovh_credentials'

Expected behavior
Correct certificate renewal.
If fields names in files have been modified, they should be upgraded when new NPM starts... Or a "Breaking warning" should be displayed on the release page.

Operating System
Linux alpine 5.10.61-0-lts #1-Alpine SMP Fri, 27 Aug 2021 05:29:55 +0000 x86_64 Linux
Docker version 20.10.7, build f0df35096d5f5e6b559b42c7fde6c65a2909f7c5

The namespaces are deprecated in certbot for a while now and that's why they have been removed. It sounds like certbot is still on an old version in your container. Could you please run

certbot --version

inside your container to seen what version you have installed? If you don't have version 1.19 or 1.20 please provide a list of other dns providers you are using, one of them could cause certbot to downgrade.

Hi,
If it has been deprecated a while it's weird I haven't had the problem before, because all my containers are automatically updated using watchtower...
I have now updated and my certbot version inside the container is "certbot 1.20.0"
I close the issue, as I have manually updated my credentials file to remove the prefix : I just wanted to open it in case it could help anyone else.
Thanks.
