+# 2024-03-20: Emergency fix
+# We were seeing cert errors inside the docker container after a new Lets Encrypt was issued.
+#
+# We know there are changes coming about root certificates and the error may be caused by that:
+# https://blog.cloudflare.com/upcoming-lets-encrypt-certificate-chain-change-and-impact-for-cloudflare-customers
+#
+# I tried installing the LE root cert's manually but that didn't work.
+# As live is broken for now we need this emergency fix, but we should remove it in the future.
