Hi, I've been running my install of ISPconfig for some time now with no real issues, currently on 3.1.15p2. The server was installed a few years back using the great "perfect server" guides. OS is Ubuntu 16.04.6 LTS. However, recently, I've been receiving emails from LE saying that my renewals are still being done with the ACME v1 protocol which will be suspended on 1st June and I should be renewing my certificates with the ACME v2 instead. Having looked at the logs, I can see that it still uses the v1 URL: https://acme-v01.api.letsencrypt.org/acme/.... Any suggestions about how I should go about updating this? Thanks.
