Manually Download Open Subtitles Not Working (Country Restriction)

[access 11]

Hello,

I've been trying to get OpenSubtitles working for a while, but can't seem to get it to work. Emby seems able to download images and update the tvdb database easily but when using the OpenSubtitle plugin and doing a manually search I get in the logs.

 

I'm running a 64bit Synology system with Emby version 4.5.4.0.

I can see it's getting a Error getting response from https://api.opensubtitles.org/xml-rpc

System.Net.Http.HttpRequestException: System.Net.Http.HttpRequestException: No route to host

This error happens when I search for Subtitles Manually when it's playing.

 

I can access the endpoint fine, and even logged into the linux terminal logged in as the Emby user and could hit that url. I can't work out why Emby can access all the other end points but fails on https://api.opensubtitles.org/xml-rpc.

 

The version of Open Subtitle installed is 1.0.27.0

 

I can hit the endpoint fine in a browser.

 

Thanks, if anyone has any guesses.

You have done a thorough investigation and eliminated all the obvious issues - so don't beat yourself up 

The error message is clearly point to a networking issue - but as proven by your tests, you can get to the URL just fine outside of emby/ the plugin.

Looking at the actual DNS IP resolution of api.opensubtitles.org - 172.67.72.143 is one of the 3 IP's...

Now, I know there has been some other topic on Emby classing any 172 address as 'local and not 'wan' (incorrectly, as the above IP is not an RFC1918 address).

So I'm thinking - if you can add a local host entry for api.opensubtitles.org to resolve to either of the other IP's (104.26.8/9.126) then it may solve the immediate issue.

If this does work - then the Dev team will need to look at this synology build, as it's classing 172.67.72.143 as local perhaps.

It may be totally unrelated of course, but this is ringing alarm bells ...

Hi, it looks like something is blocking emby server from accessing that domain. Is OpenSubtitles blocked in your country? I know they are getting banned in many places now.

OMG Luke that's exactly it. Hilarious.

The NIC the Synology server was running off didn't have the Google DNS configured, all my other machines in the house had the 8.8.8.8 as the DNS (as most Australians know to do!)

Thanks!

Thanks for the feedback.

Glad this is fixed, but your comment above now doesn't make sense - you said you could get to the site from the synology... if the DNS was blocked, then this should not have worked either ..

Probably was tested from a PC not the Synology which had the updated DNS server.  That would be my guess.

Yeah the missing piece of the puzzle is I have multiple NIC's in my Server.

The one I ssh on internally, is not the one Emby goes out on.  Only the "primary" one I had set to Google DNS not the one dedicated to Emby traffic.

Ah that makes sense - thanks for taking the time to explain.
