EDIT: I've marked this post as solved. But, whoever reads this post please bare in mind that this network error doesn't have a single solution. This is what solved my issue.

Before you read through I would advise doing very simple tasks:

  1. Test your LAN cables if you are facing this issue while connected to the network via LAN cables
  2. Restart you devices involved with you issue(client pc(s), server(s), router(s), switch(s), firewall(s) etc.
  3. Update your network drivers to the latest, update you OS with latest updates as well

I learnt it the hard way that sometimes the solution might be very simple.

Good Luck!

Hi Guys,
I'm having issues with my setup. It's been running fine since more than a year and all of a sudden I'm unable to transfer files over LAN network. It's not an issue of the file size like I've read on forums but even if the file is 2MB it still give me the above mention error. I can transfer if I'm connected over WIFI network. There's nothing that is blocking the traffic over LAN as I can stream movies from my server to my client via Plex on the Windows 10 and Nvidia Shield TV.

So far I've tried:

  1. Uninstalling Bitdefender Total Security (Client PC)
  2. Disable Windows Firewall & Windows Defender
  3. Network Reset (Client PC)
  4. Disconnected Mapped drives and Reconnected after restart
  5. Clean installed the network drivers
  6. Don't have any VPN running on my Windows 10 PC so that is definitely not the issue as mentioned in other forums After each step I've restarted the laptop.

My Ubuntu Server specs are:
HP Pro3500 G2 MT PC
Processor: Intel(R) Core(TM) i5-3340 CPU @ 3.10GHz
Installed Physical Memory (RAM): 12.0 GB
