The International Cricket Council (ICC) has blamed “technical issues” after fans were unable to vote for tickets to the 2024 Men's T20 World Cup.
The portal was open from February 1 to 7, but fans were unable to submit entries for a period of time on the final day, it said.
West Indies and the United States will co-host the tournament from June 1 to 29.
An ICC spokesperson told BBC Sport: “We are confident that the vast majority of fans were able to take part in voting over the seven-day period.”
“Due to technical issues, the ticket voting website was briefly down for a short period prior to its scheduled closure.
“This issue was eventually resolved and the ticketing portal was re-opened prior to the application submission deadline.”
According to the ICC, the problem occurred between 22:30 and 23:25 Antigua Standard Time (AST), although disgruntled supporters had reported the problem had been occurring for hours earlier.
The ICC did not respond to a question from BBC Sport asking if it would apologize to fans who missed out.
Supporters will know whether they have won the vote by February 17 at the latest, and any remaining tickets will go on sale to the public five days later.
More than 4 million people from 170 countries voted for the tournament, which has expanded to 20 teams and will feature 55 matches across nine cities.
The ICC said a “significant amount” of ballots were received from the Americas, and it was understood that these ballots accounted for approximately 50% to 60% of requests.
It will be the first time that a major ICC World Tournament match will be held on US soil, with 16 group matches to be held in New York, Dallas and Lauderhill.
The most high-profile match will be between India and Pakistan on June 9 in New York at the 34,000-seat Nassau County International Cricket Stadium, where a temporary ground is being constructed for the tournament.
England are the defending champions having won the 2022 tournament in Australia, but all their matches will be played in the Caribbean.
