"At the moment, we consider if it affects the possibilities to conduct the investigative matters and, if that is case, we shall submit a renewed request," the Swedish Prosecutor's website quoted Director of Public Prosecution Marianne Ny as saying.
The Swedish prosecutor's request to interview Assange at the Ecuadorian embassy in London was denied by the Ecuadorian prosecutor on formal grounds.
Ecuador's President Rafael Correa has said that Assange, who has been living at the Embassy of Ecuador in London since 2012, will be questioned soon, but has given no date for when that would occur.
The Swedish Prosecutor suspects Assange of rape, in connection with a visit made to Sweden in 2010. Assange was originally suspected of sexual molestation and unlawful coercion as well, but the statute of limitations on those cases has already run out.
