Describe the bug
After a bit of struggling I just updated from 2.9.4 to 2.12.3 and everything seems to work fine so far. The only issue I've had is that if I run the renew command, it tells me that the netcup plugin is not installed. It expires in a long time and is not due for renewal yet, so I assume before updating today it still worked.

When I click to renew, the log prints the following:

To Reproduce
Steps to reproduce the behavior:

Screenshots
n/a

Operating System

Interestingly, when starting the container, there's this in the logs that all seems to work fine:

Solved it with the help of the netcup dns repo. The naming got adjusted in the meanwhile (should this have been handled automatically?). So in my renew configuration I needed to replace the info before the colon (the plugin name). And the settings got renamed, so the underscored had to be replaced with regular hyphens. Now everything works again :)
