Here a bit of an update:
- I created this thread in bugzilla for Proxmox. https://bugzilla.proxmox.com/show_bug.cgi?id=7028
- I kindly ask in github to merge the PR of acme.sh
- The PR is now in the dev branch...
Maybe this link will help:

Update:
Actually it is not merged. I hope it will be soon. I'm also waiting for this :-)
