Sluggish home network acces


Best Answer jlr19 , 13 November 2019 - 11:14 AM

My OP issue has completely stopped for now, I can now access emby "1" from pc "2"  reliably and just fine, but...

 

see: https://emby.media/c...-emby-for-kodi/

 

pc "2" and "3" have coincidently stopped connecting their identical respective Kodi/Emby for Kodi setup's to Emby "1".

 

Can you say ghost in the machine ?

For the last 3 days or so, I have a difficult time to access Emby from my home network.

Emby server runs on computer "1", and if I access Emby directly from the host computer "1", everything seems normal.

 

However, if I try to access Emby from computer "2", I either get just the Emby logo, or spinning circle  and/or mostly incomplete page content.

Computer "2" is my main workhorse computer and is otherwise not showing any issues. It also runs Emby for Kodi without issues

 

Computer "3" is my htpc and it can access both Emby web and Emby for Kodi just fine.

Computers "1" and "2" have been restarted multiple time trying to get them to fix the issue, to no avail.

 

I am running Emby v 4.3.0.21 beta and I believe my access issue started soon after last update.

I do not use or need Emby from outside my home.

All 3 computers (mentionned above) are ethernet wired.

 

As I type here, Emby has been trying to open for at least 20 minutes, all I see is a 90% black screen, the Emby header and the spinning circle. PC's "1" and "2" are essentially idle (cpu, memory). Server show 0% Emby cpu usage.

 

After the last of 20 or more F5's, the home page fully loaded within a second. This is the "non-pattern" I've observed since this started 3 days ago. It will not load (or be 90% crippled) for hours, then be back blazing fast as if nothing happened.

How is computer 2 connected to the network?

 

Have you installed anything new on that machine?

 

It is highly unlikely this is an Emby problem but please post a server log with specifics on what you tried to access and when.

All 3 computer wired ethernet.

When pc "2" (workhorse) can't load/use Emby (installed on pc "1" along with media collection), it can access all the same content thru Windows Explorer.

Business as usual for both Emby host and client.

Will post log shortly.

 

Here's the log but like the classic dentist running gag, Emby presently loads normally.

I will repost a fresh log when issue resumes.

Put your log in debug mode and restart the server before testing.

 

Thanks.

Can you access 2 from 1?

If you mean embyweb to emby server, its now OK, yes (but I don't have a clue why it stopped and then resumed working).

 

But I now have a different problem, "2" and "3" wont connect to 1 thru kodi/emby for kodi.

While I realize this is not a Kodi addon thread, the fact I have 2 machines showing exactly the same symptoms lends me to believe the problem is with Emby not "letting them in".

If 2 and 3 never have problems communicating, then I'd suggest checking network hardware for 1. Cables and ethernet ports. It's sounds like something is failing.

Wouldn't that cause problem outside of emby ? My internet connection is perfect, all 3 pc can be accessed from each other  from windows explorer, both shared drive and home network browsing all work fine.

Hi,

 

I'll post this. A bit out of the blue. :)

 

List of things (kind of advanced stuff) I check if I have any trouble like this. Check this on the computer running Emby.

 

  • Package loss / transfer rate. Check with speedtest.net
  • Inbound TCP connection limit (I see you are using Windows 7 for Emby) this limit can be hit quite fast. And the limit is ~20 concurrent clients / connections. I hit this wall couple of times. There are workarrounds.
  • Windows Firewall (if you do advanced stuff here) a network change can invalidate approved adapters connected to a rule. Like when updating drivers / changing workgroups aso. this can happen.
  • Du you have IPv6 in addition to IPv4 on your LAN? Some WAN / NAT routers (old ones) get confused here on the LAN.

 

-M.

First results is from very new pc "2" I am getting speeds 13% over advertised (50/400)

5dcc3689577b6_Capture3.jpg

 

This from the older win7 "1". An obvious loss of dl, but IMO still sufficient to get things done 

5dcc36981aa83_Capture4.png

 

Those 2 pc are side by side, wired to same ethernet switch and router.

 

Edit: forgot to say we're still in ipv4 neck of the wood.

And I never go near the windows firewall settings/rules/etc

Hi,

I have seen the same issue by not all content loading in the Emby Web UI where I hit the rate limit when I was also watching some content on another device (not direct playing but streaming).

 

I would try to disable TCP/IP rate limiting.

 

Disclaimer: this is involves modifying the registry so you should be very careful.
 

  1. On the machine running Emby Server open "Registry Editor" (regedit.exe) (search for it in the start menu).
  2. Navigate to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters"
  3. Look for a key named "EnableConnectionRateLimiting" and set it to 0 (zero).
  4. If it's missing create a new DWORD named "EnableConnectionRateLimiting" with the value 0
  5. Reboot

-M

When I had the problem earlier, the home network was almost dead still. No streaming, no down/upload, even their respective task mgr's were basically idling.

I'll leave the registry alone for now. :)

Sure. :) This is just my theory of your issue.

 

The reason the rate limit can hit is if a computer is behind a NAT-router and running multiple applications accessing the network (externally). Mostly long running connections.

 

Windows 7 is not actually made for hosting stuff (as a webserver). This is the TCP stack in Windows and not Emby. But Emby struggle when hitting the limit. This have actually changed a bit in Windows 10. Microsoft have loosened up this TCP limit a bit.

And this pc running win7 and emby server will more than likely be replaced around next tax return; new mobo-cpu new fresh install OS.
