huh, same chrome here and ive about gave up.I am using Google Chrome (Version 70.0.3538.77, 32-bit). I also just checked Internet Explorer 11 and it worked as well.
Even turned off my antivirus and malware software.
Ive tried on several machines as well using different browsers. Mint 19 with cinnamon linux machine, XP, Virtual PC on Win 7, Win 8.1 and Win10 OS.
Thats why I really thought it was an issue with the ODT server software
