NHS Digital also tweeted: "There are currently issues with accessing the Covid Pass on the NHS App and website. We are investigating the issue and will update as soon as we can."
One traveller hoping to go abroad replied: "Cheers guys missed my flight with it."
Others replied concerned they wouldn't make their flights later today.
One said: "Is there any estimation of how long the fix will take? Due to travel in 4 hours time, but won't be if the app isn't working again."
Another added: "On a flight in half an hour, what do I do?"
