Bobi Wine has told reporters that he believes the internet and social media shutdown is being used to block communication and as a way of compromising the vote.
The opposition presidential candidate has already alleged there was rigging and his agents and representatives have continued to be arrested.
But the chairman of the electoral commission, Simon Byabakama, has said that the onus is on Bobi Wine to provide evidence that there was rigging.
Only two polling stations in the country reported major irregularities and voting was cancelled there. At one of the polling stations, someone run away with a ballot box.
