During mirroring will the site make a call out to the Mirroring service (a separate application), the error seems to be caused in the service. Could you try to enable logging for the MirroringService to get some more information about the cause (e.g. a stack trace)?
You can do this by adding a EPiServerLog.config file (e.g. copy it from site root) to the mirroring service folder (typically MirroringService folder in your site root).
Hello Johan
I enabled the serrver log on Mirroring Service and found the following
2015-07-27 09:58:10,709 [17] ERROR EPiServer.MirroringService.Common.InitializationServiceContext: Failed to initialize EPiServer runtime from config: Object reference not set to an instance of an object.2015-07-27 09:58:10,746 [17] ERROR EPiServer.MirroringService.Proxy.RuntimeMirroringProxy: Object reference not set to an instance of an object.System.NullReferenceException: Object reference not set to an instance of an object. at EPiServer.MirroringService.Common.InitializationServiceContext.InitalizeEPiServer(ProxyContext context) at EPiServer.MirroringService.Common.InitializationServiceContext.InitializeEPiServerRuntime(ProxyContext context) at EPiServer.MirroringService.Proxy.RuntimeMirroringProxy.Initialize(ProxyContext context)2015-07-27 09:58:10,856 [17] ERROR EPiServer.MirroringService.MirroringSourceService.MirroringSourceServer: EPiServer.MirroringService.MirroringTransferProtocol.Common.MirroringFaultExceptionDetail

Make sure that assembly bindings (mirroring web.coinfig) and mirroring bin folder are updated as well.
