error code 20512, 20496

I have been trying to re-download game for over a week now. Every time I log in the launcher will start updating the patch and get between 4-40 MB of data downloaded then the launcher will crash stating unable to download patch. Error 20512 20496

The link below has this listed as a resolved issue. It is not resolved.

I have tried setting up static DNS ports, DMZ my PS4, cold restarting all systems, factory resetting router, modem, PS4. The Download of FFXIV heavensward patch data from ex1-2015.05.26.0000.0000 on just does not work properly and has to be downloaded in tiny MB intervals. Then if I am lucky randomly FFXIV launcher will forget I have started and almost completed the HW download and will just start back over from scratch. It has been a week of trying 8-14 hrs a day trying to get this game re-downloaded, please fix this.

Other fixes that have been listed by SE support emails in other threads with regards to this have proven futile and do lot work, some of which include: ensure signal strength above 75% (constant95-100% strength), power down PS4 and router then let the router fully boot up before turning on PS4, and restoring default settings on PS4.
