Error in downloading PDF file from ABL Code

When I run a test with the routine indicated by Progress to download a PDF file, I have the following problem. Some files download correctly, others bring only one part, and therefore the file is invalid.

I did the test with 2 random links, where one of them is correct, and the other one has an error.

Has anyone ever come across this situation?
