Emby fails to make https connections to external servers

[manatails 2]

After updating from 3.x to 4.0.3.0, my Emby server fails to connect to most of the external servers.

 

Not sure exactly which version started causing this, because I have updated emby several times before noticing this bug. But I am sure it started after 4.0.x

 

update checking, metadata downloading are all broken.

 

When I inspect embyserver log I get the following:

If I just visit the link in my browser it works just fine.

Hi there, can you make sure you don't have anything blocking emby from making those connections, such as firewall, security software, vpn, etc. Thanks.

Yes, I just checked that the same thing happenes with the firewall completely off.

[manatails 2]

Also I noticed that I get

While starting the server.

Do you have any security software or a VPN? I can only tell you what I am seeing. I can't tell you why this is happening as that is specific to your local environment, but I can help you with common reasons why it might occur.

[rbjtech 5284]

A network 'time out' suggests a routing issue.

 

Cut and paste those https links into your browser - if they do not work, then that is why emby is not working either.

 

ie

To note - the above works fine for me - so I think you have network issues.

[Luke 42078]

Yes that's a good thing to try, and if it does work, then it suggests you have something blocking emby server from making those connections, such as firewall, security software, or vpn. Thanks !

[manatails 2]

I already stated that other connections from the same computer is confirmed working...

 

I am a bit too occupied at the moment, but anyway I will try reverting to previous version and update the post.

I've done some tests. I kept uninstalling and reinstalling until I found a working version. I can confirm that it is Emby problem.

 

Last working version is 4.1.1.0.

 

The bug starts with 4.2.0.40

 

 

I am using Windows Server 2008 R2 as host.

[Luke 42078]

Are you behind a vpn?

[manatails 2]

Are you behind a vpn?

 

No, it is safe to assume that all network related possibilities have been ruled out.

So are you saying all requests are timing out or just some?  But I know I don't see any of the image time outs from TMDB, but don't use Windows 7 either if that is relevant.  WHS 2011 and Windows 10

All requests seem to be timing out.

Just a guess, but does your server by chance have a IPv6 address?

I disabled IPv6 from all installed ethernet adapters, but it did not work...

I'm really thinking that has to be the issue because I saw it on one machine as well.  As soon as I disabled IPv6 on the server's adapter, the problem went away.  Are you sure you got that disabled on the server?  Did you try restarting after that?

Still same after a reboot

[manatails 2]

I fired up Wireshark to see what is happening,

 

It seems that Emby doesn't even send any packets to the server.

EmbyServer queries DNS for server ip address, then it doesn't start any sort of connection to the server, waits about a minute then fails with timeout error.

[rbjtech 5284]

So does it get a DNS response ?

[manatails 2]

So does it get a DNS response ?

 

Yes it does get a DNS response

[rbjtech 5284]

Yes it does get a DNS response

 

ok.   Have you tried a fresh install ideally on another machine - or even the same machine if using the portable version (obviously setup to use a different port) ?

 

This must be a machine/infrastructure specific problem or there would be 1000's of issues being reported...

I already stated that I've tested many different versions:

 

versions before 4.1.1.0 work flawlessly

versions after 4.2.0.40 have this problem

even the initial setup takes a long time because it waits for a response from Emby update server (which eventually times out).

This points to it being related to .net upgrades within our product.  So, be sure you have the latest .Net installed.

 

I know the IPv6 problem is likely a .Net issue introduced in one of their upgrades.

[Luke 42078]

Try disabling ipv6 in your router.
