The Soyuz was commanded to back away from the station after approaching to within 100 metres of Poisk when the vehicle could not achieve a solid telemetry lock to that docking port through the automated rendezvous system, NASA said in a blog post.
ISS managers and the international partners approved the plan to allow a second rendezvous and docking attempt for the unpiloted Soyuz MS-14 spacecraft to occur on Monday night.
Russia launched the spacecraft carrying its first humanoid robot astronaut into the ISS on August 22.
The robot -- named Fedor (Experimental Demonstration Object Research) -- is the first ever sent into space by Russia.
The humanoid robot is 5 feet 11 inches tall and weighs 160 kg.
