I can't help you much, but for thoughts:
what exactly kernel version you use?
do you use vswap configs for CTs?
do you see failcounter increase?
what distro is in CT?
do you tested problem with HN ( I assume you see problem only with CTs)
do you see same problem with stock kernel. You mentioned proxmox, so probably best way would be use rhel kernel (distributions centos, scientific linux), not debian.
maybe HN is running some network shaping stuff?
eliminate as mush as possible network hops (switches, routers, etc.)
as long as you can't exactly say how to reproduce problem it will be hard to solve problem.
btw, network equipment vendors and models can also help solve problem.
as example I recently debuged problem when in random times same file download with http had problems. problem was with cisco firewall and some settings.
