British Judge Emma Arbuthnot said she was "not persuaded" the warrant should be withdrawn, according to the AP.
Mr Assange has been living inside the Ecuadorian Embassy in London for more than six years following a sex assault-related case brought by Swedish prosecutors.
The Metropolitan Police Service (MPS) said the incident was "stood down" after the package was assessed.
A courtroom defeat means Assange still faces arrest for jumping bail, although British police no longer maintain a round-the-clock security presence outside the embassy. He has refrained from leaving, he said, because he fears that if he does, the British government will extradite him to the United States, where he is facing multiple charges for leaking classified information.
After the decision, Assange's lawyer Mark Summers asked her to consider whether it would be in the public interest to continue pursuing his client for breach of bail conditions.
Judge Emma Arbuthnot said she would give her decision on February 13.
The offence carries a maximum penalty of one year in prison, and Assange remains in the Ecuadorean Embassy.
"His health issues are not that bad", said Arbuthnot. Last year, WikiLeaks released documents detailing USA government hacking tools.
However, the court announced on Tuesday his application had been rejected.
It is not publicly known whether there is a sealed US indictment against Assange.
Earlier this month the United Kingdom government refused to grant Mr Assange diplomatic status and called on him to leave the embassy to "face justice". However, with the arrest warrant upheld, Assange can't step onto the streets of London without risking arrest.
Assange tweeted to condemn "wall to wall fake news stating the government won today's hearing", insisting his legal team was still fighting the warrant on other grounds.
Sky's David Bowden, at the court, said the judge was now looking at case law to see if she could consider the reasonable cause argument without Assange present.
But he added, "I think it confirms all the reasons to be concerned about polar bears from a conservation perspective are intact". Scientists monitoring the creatures activity in the Arctic found they have far higher energy demands than previously thought.
