Tickets to the grand final of the Eurovision Song Contest in Liverpool sold out in just over half an hour on Tuesday morning.
Fans faced technical issues as the Ticketmaster website struggled with the number of people trying to secure tickets to the nine different live shows.
The dedicated website page appeared to crash shortly before tickets were due to become available, with issues continuing throughout the sale.
Some were met with a "500 - Internal Server Error" message when they attempted to click through to find tickets.
Others reported being ejected from the virtual queue after receiving a message saying their session had expired "due to inactivity".
At 12:36pm, the official Eurovision account tweeted that all tickets to the grand final had sold out.
It added: "Tickets for other shows are still available but demand is high!"
The international singing competition will take place at the 11,000-capacity Liverpool Arena in May, culminating in the grand final on 13 May.
Ireland will be represented by the group Wild Youth at the contest.
The Eurovision is being held in the city after the UK was chosen to host the competition on behalf of war-torn 2022 winner Ukraine.
Tickets for the semi-final shows are priced from £30 to £290, with the cost increasing to between £80 and £380 for the grand final shows.
There will be six previews and three televised shows.
The evening preview show - previously referred to as the jury show at past contests - is a dress rehearsal-style full run-through of the show that takes place the night before the televised version.
Audiences attending the evening preview will be able to stay for a randomised version of the qualifier and points reveal, which gives the presenters a chance to practise for the possible different outcomes.
Eurovision is set to air on RTÉ and the BBC and will be hosted by singer and Britain's Got Talent judge Alesha Dixon, Ted Lasso actress Hannah Waddingham and Ukrainian singer Julia Sanina, as well as returning favourite, comedian and talk show host Graham Norton.
The semi-final evening preview kicks off at 8pm on 8 May, with the grand final live show bringing the contest to an end starting at 8pm on 13 May.
Ukrainian refugees living in the UK through the Homes for Ukraine scheme, the Ukraine Family Scheme and the Ukraine Extension Scheme will be able to apply for cheaper tickets.
It was previously announced that the UK Government will make around 3,000 tickets available for those who were forced to flee their home country when Russian troops invaded last year.
The subsidised tickets will cost £20.
