Ubuntu Server 16.04.5
After update to 1.5.3 I changed the IPs connected to the server via I-MSCP-Admin-Panel for all hosted Domains local and on the Name-Servers of my Domain-Provider. All the Domains are reachable, but any subdomain is. The subdomains are connected under the IP of the main domain and show up under the right IP if pinged. Adressed in a browser the 'Server Default Page' shows up, whilest the main domain works like a charm. What's wrong?
