Error when downloading document from the GGIS

[EliVolsch]

Good afternoon,
We were reached out by one of our users saying that they cannot download a document from the GGIS. I tried to do it myself, and for me it doesn't work either:

The document is this one: https://ggis.un-igrac.org/catalogue/#/?q=5s%20-%20boa%20vista&f=document&d=1715%3Bdocument

Can you please check what may be the problem? Thanks
