• Some domains are not working on the server

• The server was upgraded from some old version of Plesk, e.g. 11 or even older, or the domains were migrated from

• There are entries in psa.hosting table where same_ssl is set to false:

  CONFIG_TEXT: # plesk db "select count(*) from hosting where same_ssl='false';"
  +----------+
  | count(*) |
  +----------+
  | 13 |
  +----------+

  which means that "Separate SSL/TLS and non-SSL/TLS content" option was enabled for some domains in their hosting settings on old Plesk server.
