Push Notification not received when using in Load Balanced Servers

[ghulamostafa]

I am not sure if I should be writing it here or not but maybe fellow developers faced it before.

I have created a DLL file of my own that wraps the firebaseNet nuget package. For simplifying I have made a Method to accept few arguments and send notification to all users [Fetched from database] in an ASP.NET application. This method works absolutely fine for me when I am using it in a single server. But if I do the same in a Load Balanced Servers [Application Request Routing (ARR)] the notification simply never reaches the client. Even though there are no errors or exceptions.
