GRO certificate - problem downloading

[ElizabethHerts]

I ordered a PDF of a death certificate and it is available now.
However, when I try to download it by clicking on the View PDF button, it firstly says "Paused" and then "Couldn't download - Network issue".

I don't have any problem with my internet connection and have downloaded other files today.

I'll try again in the morning but it's very frustrating. Any suggestions welcome.
