It's not strange at all. When using static file names nginx opens these files
at startup, before changing uid/gid from root to nginx. When using dynamic file
names that, obviously, can't happen - nginx has to open these files at request
time. So if you didn't configure Certbot to install certs with correct
owner/perms then it can't and won't work.
