Can't connect to Emby server remotely

[Tannhauser 0]

Hi

I know this question has been asked numerous times, but I have already read two Emby connection guides and some other forum posts regarding the same issue to no avail. My issue is simply that I can't connect to my Emby server remotely. I have followed these guides:

• https://support.emby.media/support/solutions/articles/44001849007-connectivity
• https://support.emby.media/support/solutions/articles/44002137137-remote-setup

Right now I'm stuck at the "traceroute" command, as I'm a bit unsure how to read the output:

The site canyouseeme.org shows the correct IP (WAN) as is shown on my server dashboard. When entering the port 8096 or 8920 I get the message: "Error: I could not see your service. Reason: Connection timed out".

Here are my other settings:

Emby network settings

The second hop is not a good sign. It looks like double NAT.

Thanks for the reply. What does double NAT mean, and can I solve the problem in any way?

It means that your private network and router (192.168.1.0) are behind another private network and router (192.168.87.0). More often than not because someone installs a personal router connected to an ISP router. Usually can be fixed by changing the provider's modem/router to bridge mode or configure DMZ.

In your case hop 3 is also a private network (100.76.0.0) so even if you fixed hop 2 your provider might be using CGNAT. If your provider can't give you a public IP address for your WAN connection then the solutions get more complex.
