Problems with outgoing connections, such as identifying movies/tvshows

[math5969 0]

Hi, im having problems with my Emby server, running on Linux.
Out of nowhere, my server started having problems recognizing Movies and TV-Shows, as well as searching for images.
I noticed as well, that I couldn't add Emby connect users to my local users, at least for one user, haven't tried with others, since they already have their emby connect user connected.

I have attached the error log from the server, in which I noticed this exception at line 8314: 

System.Net.Http.HttpRequestException: System.Net.Http.HttpRequestException: An asynchronous socket operation is already in progress using this SocketAsyncEventArgs instance. ---> System.InvalidOperationException: An asynchronous socket operation is already in progress using this SocketAsyncEventArgs instance.

 
 
Hope someone can help me
Thanks

Very strange yes, all outgoing communications are failing. Do you have anything configured on your server machine that might be causing this? Firewall, security software, vpn, etc?
