Synology / Docker / VPN / Transmission > Upload issue/s

[pixelrogue]

Newly minted docker/media server on synology and no uploads are barely a trickle through transmission....topping out at 25 kB/s. Download speeds fine, upload terrible-to-non-existent. Below are datapoint that might help...

DATAPOINTS

• Synology is running through Docker.
• Docker is running an OpenVPN certificate.
• No known transfer limitations on vpn, transmission settings, docker settings. DL ok, UP = terrible.
• Transmission settings
  • Torrents = defaults - no seeding radios or stops when idle
  • Speed = defaults - no speed limits
  • Peers = defaults + All options (PEX, DHT, LPD) are enabled. No blacklist.
  • Network = listening port closed, uTP enabled.
    -----
  • Portainer > Transmission > Container stats ~ shows a little heavy on ram (using default 2 atm, will upgrade later this year). Speeds remain slow w/other services disabled.
  • Portainer > Transmission > Logs ~ series of repeating errors, mainly DHT announce failed (firewall, 540 nodes) & IPv4 DHT announce failed (firewall, 540 nodes.)

  •  IPv4 DHT announce failed (firewalled, 541 nodes): Invalid argument (/home/buildozer/aports/community/transmission/src/transmission-3.00/libtransmission/tr-dht.c:737),

  • ping & trace route appear to be working fine...nothing there to determine upload speeds or blocks.
    
    
• On the Mac, using desktop transmission w/the same open vpn certificate, upload working as expected.
