As far as I know, they're identical. And are both grammatically correct and can be used interchangeably.

Is this indeed the case?

They can be identical in meaning, but that's not always the case.

No puede conectarse may always be rendered as No se puede conectar due to the phenomenon of pronoun raising of Spanish. In this case, the se is associated with the verb conectar, but may be placed either with conectar (enclitically, because it's in the infinitive) or poder (proclitically, because it's conjugated).

However, se need not necessarily be associated with conectar. It is also possible that the se is associated with the verb poder, forming an impersonal statement. In this case, because pronouns can only be raised and not lowered, there is no other alternative rendering and only "no se puede conectar" works.

  • what'll be the difference in the meaning when "se" is associated with conectar and when with poner?

    With conectar, "[something] is unable to connect (itself) / get connected". With poder, "It is not possible to connect / One cannot connect" Sep 26, 2018 at 4:14

    I'm saying that no se puede conectar has two potential interpretations, only one of which is equivalent to no puede conectarse. As such, no puede conectarse can always be rewritten as no se puede conectar, but no se puede conectar cannot always be rewritten as no puede conectarse. Sep 26, 2018 at 13:00
  • @guifa La diferencia es cuando uno quiere usar ‘no se puede conectar’ como impersonal?

Yes, they are the same.

Also you can say:

No se conecta

Even informally (opinion as native spanish speaker) No conecta

  • You can check the popularity of each for googling "No conecta" / "No se conecta" / etc and looking at the amount of results.
