Hey guys, My old machine needs to be replaced, so I try to migrate all websites to a new host, running the latest ISPConfig 3.2.11 and Debian 12. My migration scenario is classic: Migrate the database, modify the config.php to connect to the new DB, then migrate the files, then change DNS, done. However, I noticed one site is behaving strangely. I have a domain named example.com, and a nextcloud instance located under cloud.example.com When I change the DNS records (or the /etc/hosts on my desktop), and I try to access cloud.example.com, I get redirected to example.com. I have set up the new environment exactly like the old one, but I can't figure out the reason. The logfiles also show me no clear indicated on why this is happening, so I am - to put it bluntly - dumbfounded. Has anyone an idea what I could try to solve this problem? Reboot of the server didn't help, clearing my cache didn't help.... Thanks in advance. Kind Regards Zero
Perhaps certificate issue? Did you migrate them to new host or create new certificates on the new host?
