Some pdfs downloaded is password protected.

[ER-EPR]

I'm using fork branch fixgetpages from @motoyugota , it works most of the time, thank you very much, it helps me a lot.
I subscribe to a magazine but several issue of the magazine can't be combine to one pdf. The error is as follows.

.retrying after error: pdfcpu: please provide the correct password
Removing extra pages failed with pdfcpu: please provide the correct password

And the pages downloaded is all password protected. I can't see any patten, seems random, totally.
An example of the password protected pdf looks like this. And if I skip the password protected issues, other issues can be downloaded quite fine.

         Someone mentioned it in another bug report:

And indeed, while this script is running, all the temporary .PDF (inside the issue/ folder) have a password (if i try to open one with evince : i can't).
They however have a "regular" size (= are not empty, ...), like several hundeds of kb.

The resulting / final PDF in the end is sadly empty (0 bytes).

My config file is just :

{
 "username":"XXXXXXXXXXXXXXXXXXXXXXXX",
 "password":"XXXXXXXXXXXXXXXXXXXXXXXX",
 "chromepath":"/usr/bin/google-chrome-stable",
  "fingerprint":"XXXXXXXXXXXXXXXXXX"
}

I am using the same fork, and am also getting password prompts on all my pdf files. ZiniGo is failing to combine the pdfs.
