I've moved this to discussions. If you think this is a bug in mitmproxy, then file a bug report and fill out the full template.

Open the regular proxy on my computer

mitmweb --mode=regular@18089 --ssl-insecure --set block_global=false --showhost --set confdir=./conf

set iptables rules in phone

sysctl -w net.ipv4.ip_forward=1
ip6tables -t mangle -A OUTPUT -m owner --uid-owner u0_a269 -j DROP
iptables -t nat -A OUTPUT -p tcp -m owner --uid-owner u0_a269 -j DNAT --to 192.168.8.139:18089
iptables -t nat -A OUTPUT -p udp -m owner --uid-owner u0_a269 -j DNAT --to 192.168.8.139:18089

FLV is a live video stream format. It can be well forwarded on Charles, maintaining a long connection, but it disconnects on mitmproxy.

Can this be reproduced on a desktop as well (would be much easier)? What website do I need to open and what needs to be done to reproduce the error?

you can pass --set stream_large_bodies=1 when using the mitmproxy
