Docker networking issues

[lonewolfnight 0]

First time install w/ docker 18.03.01, 

 

Seems to have issues initiating certain connections to the outside world. Server is publically accessible and does register with Emby account. 

 

Web API's are accessible from the server directly. 

 

"Check for plugin updates failed"

 

"Check for application updates failed"

 

 

1.  
2. System.Net.Http.HttpRequestException: No such device or address ---> System.Net.Sockets.SocketException: No such device or address
3.        at System.Net.Http.ConnectHelper.ConnectAsync(String host, Int32 port, CancellationToken cancellationToken)

 

 

 

Numerous network errors are being thrown in the server log after first setup using current Docker image.

Hi, your outgoing network communications are failing. Have you configured a network connection for the docker container?

I believe so, The docker ip is reachable from internal LAN.

sounds like an outbound firewall restriction.

As per the paste bin, the outbound firewall is ACCEPT default.
