Websocket Errors in Dalamud xllog

[raegx]

These error messages occur on every startup for me.

As far as I know, this plugin is the only one that uses websockets.

Please check your websocket plugin settings in your OBS, and also https://github.com/Bluefissure/Dalamud-OBS/issues/19

I see what the issue is.

I configured XIVLauncher to terminate OBS on close. However OBS does not like this and on next run will show a safe mode prompt before fully starting:

In this case, the stack trace above is output when FFXIV Loads. Additionally, once the above prompt is bypassed, another exception will occur:

14:03:09.004 | ERR | Unobserved exception in Task.
    System.AggregateException: A Task's exception(s) were not observed either by Waiting on the Task or accessing its Exception property. As a result, the unobserved exception was rethrown by the finalizer thread. (The requested name is valid, but no data of the requested type was found.)
     ---> System.Net.Sockets.SocketException (11004): The requested name is valid, but no data of the requested type was found.
       at System.Net.NameResolutionPal.ProcessResult(SocketError errorCode, GetAddrInfoExContext* context)
       at System.Net.NameResolutionPal.GetAddressInfoExCallback(Int32 error, Int32 bytes, NativeOverlapped* overlapped)
    --- End of stack trace from previous location ---
       at SonarUtils.HappyHttpUtils.PerformDnsAsync(List`1 entries, AddressFamily family, SocketsHttpConnectionContext context, CancellationToken cancellationToken) in /work/repo/SonarUtils/HappyHttpUtils.cs:line 100
       --- End of inner exception stack trace ---

The first attempt after this point will result in an authentication failure then a follow up attempt which will succeed.

The plugin does work in this scenario, it just doesn't appear to be handling the safe mode prompt edge case well.
