The problems with the CoronaCheck app seem to be over on Sunday.

The app, which has been used as a ticket for restaurants, cinemas and events since Saturday, was immediately overloaded on Saturday evening due to large crowds and a DDO attack.

Due to the outage, users of the app were not shown a QR code.

The servers of the CoronaCheck app are no longer being attacked, a spokesperson for the Ministry of Health, Welfare and Sport (VWS) reported on Sunday.

Creating a QR code should no longer be a problem.

It is unclear who is behind the attacks, the spokesperson said.

In a ddos ​​attack, an attempt is made to make a website, server or service inaccessible.

A computer system is visited so massively through a network of hacked devices that it crashes.

To create the QR code, the app needs to connect to the internet once.

That happened in many places at once on Saturday night.

According to the ministry, the servers of the app had been scaled up to handle large crowds.

Koninklijke Horeca Nederland (KHN) reacted disappointed to the problems with the app.

"In the summer, things also went wrong with apps that do not work properly," sighed chairman Robèr Willemsen.

"Now there are long lines everywhere with dissatisfied people. In this way, the government makes it very difficult for our industry."

Complaints were also pouring in on social media and the government app was mocked.

People who still wanted to go out could download the QR code at home.

The code will then remain available offline.
