Comment (by AVee):

 It's not just DNSPort:
 Apr 11 20:37:37.000 [notice] Opening OR listener on xx.xx.xx.xx:443
 Apr 11 20:37:37.000 [warn] Could not bind to xx.xx.xx.xx:443: Permission
 denied
 Apr 11 20:37:37.000 [notice] Closing no-longer-configured OR listener on
 0.0.0.0:443

 As a fix, what's wrong with just closing the old port before opening the
 new one?
