You can try forwarding the below list of domains for your IT team to whitelist on your network/firewall:

  • cdn.ipaper.io
  • viewer.ipaper.io
  • embeds.ipaper.io
  • admin.ipaper.io
  • ipaper.ipapercms.dk
  • tools.ipaper.io
  • docs.ipaper.io
  • help.ipaper.io
  • spf.ipaper.io
  • ftp.ipapercms.dk

All domains should have ports 80 (HTTP) and 443 (HTTPS) open.


If you use iPaper FTP server (ftp.ipapercms.dk), you should also open ports 20+21 (FTP).
