Fixing SignalR Max Connection Limit Issue

SinglaR does not have any limitations of concurrent connections. We need to set the IIS aspnet.config

Please open path: %windir%\Microsoft.NET\Framework\v4.0.30319\aspnet.config and add/change the maxConcurrentRequestsPerCPU property of the pool. 

<system.web>
    <applicationPool maxConcurrentRequestsPerCPU="20000" />
</system.web>
