Http response blocked during download, repeatably

Hi, is it possible that the router blocked this HTTP download repeatedly at the same specific file location and dropped the remaining packets?
Restart of router didn’t help, using LTE phone thether got me over the failed chunk file. This is part of Epic Games Civilization VI.

  • it always stops at this place in the file and the http connection is dead. Full file has 133KB

Perhaps some anti-malware on the client doing packet inspection and interrupting the download -> acting different on the tethered connection?

curl -vo /dev/null CA27B86A385_98E71337400A8CEDC891A3BF5B4355BE.chunk

on the client as well as on the router itself.

I got the full 133k via Turris Omnia, TOS 4.0.5.
