Final 700MB of 5.5 PC patch downloading extremely slowly

[MarcusU]

I was able to download approximately 90% of the patch overnight; however, at 700.98 MB remaining, I got an error "Unable to download patch files. [30413][25008][10009]." I have since managed to recommence the download, however the download is happening at an extremely slow rate, ranging from 0.03MB/s to less than 0.01MB/s; this is in contrast to my usual speed of 0.25MB/s or so, half that when my fiance and I are both downloading patch files.

Yes, I do have slow internet, but this incredibly slow rate is unique to the FFXIV download alone, and only on the last 10% of this specific patch. Anecdotally, I've also heard from a few other people experiencing the same issue.

Data I do have:

ISP: CenturyLink (DSL) in the upper Midwest
Speed test result: 3.14 Mbps, or 0.39 MB/s
Platform: Windows 10
Launcher version: 2021.03.26.0000.0001 (6182915)


Edit: Fiance got up and checked his download; it failed at the exact same point (700.98 MB remaining) despite his download starting later than mine. If the issue was related to our network, he should have had more left to download than me.
