Yesterday we started rolling out a pre-configured Let’s Encrypt automatic renewal and configuration mechanism based on dehydrated. We noticed a bug in our SSL config generation script that made it impossible to load certificates for more than one domain. This has been fixed now.
If you ran in to this problem you can re-run dehydrated -c (or just hypernode-ssl-config-generator).
Additionally we again made some changes to our Web Application Firewall (WAF). If you notice something out of the ordinary or think this new configuration is somehow impacting your user defined Nginx configuration, please contact us.
