Timed out connection when download subtitle or install plugin

[lucis13 1]

Hi, recently my Emby server (ver 4.8.10.0, installed on DS220, Synology 7.2) cannot download subtitle and install plugins due to timed out connection. I got the following log:

The emby server can still scan my movie on my NAS, and download metadata.

Please help me to resolve this issue. I'm quite new on this, so if you need more information, please guide me.

Hi, typical causes of these connection failures are firewall, security software, or VPN. Can you look into those and let us know what you find? Thanks !

[Carlo 4560]

Hi, another cause could also be a congested Internet connection. For example, if you have/use a torrent/usenet downloader or have others in the house swamping your Internet connection.  As Luke mentioned, VPN software is often a problem we see with connection problems.

What do you see if you try and Trace Route embydata.com and api.opensubtitles.com from the server machine?

[lucis13 1]

thanks @Lukeand @Carlo, may I ask how to trace route from my synology nas? Also, I don't use any VPN, what is the other settings that could affect my connection?

Do you have Synology Quick Connect activated? Isn't that itself also a vpn?

[lucis13 1]

No, I don't enable Quick Connect. The emby subtitle downloading was working fine, until recently. I don't know if I tweaked some settings or because of updating it to a new version

Do you know how to access the command line?

[lucis13 1]

Please help me with that, I don't know how to access the command line

[Carlo 4560]

Actually, I think you can do it in the GUI.

[lucis13 1]

I think that's guide is for SRM, not DSM. Anyway, I have managed to use the terminal, I can ping google.com, emby.media from my NAS, but not embydata.com (100% packet loss)

[lucis13 1]

I notice that when I ping embydata.com from my NAS, it resolves using IPv6: 

ping embydata.com
PING embydata.com(2606:4700:3031::ac43:94a6 (2606:4700:3031::ac43:94a6)) 56 data bytes
^C
--- embydata.com ping statistics ---
13 packets transmitted, 0 received, 100% packet loss, time 1011ms
 

If I ping on my computer, it resolves using IPv4:

ping embydata.com

Pinging embydata.com [104.21.95.214] with 32 bytes of data:
Reply from 104.21.95.214: bytes=32 time=60ms TTL=51
Reply from 104.21.95.214: bytes=32 time=60ms TTL=51

Then I try to ping 104.21.95.214 from NAS, it works.

Hope this can get you more insight

[Luke 42077]

Can you try disabling ipv6 in your router?

Or just disable it on Synology itself.

[lucis13 1]

nice, I disabled the IPv6 on my Synology NAS, it worked like a charm

[Carlo 4560]

Glad you got it working.

[lucis13 1]

this is just for my curiosity. May I ask why it stopped working like that?

[Carlo 4560]

Most likely the IP4 stack had priority over IP6 and something changed it.

I think the http stack in the dotnet runtime is trying to use ipv6 when it thinks it's available, but then you're unable to reach that domain that way.
