I have developed a C# ASP.NET Core Web App using SignalR for real-time communication. I am running the application on local IIS with a public IP address. On the same network, I am able to access the site from my phone using the public IP address, and of course, I can access it from my computer as well. I can also connect to the SignalR hub from Unity (on my computer) using the same IP address. However, I am unable to connect from my phone(android) to hub with the same unity app, and I am not receiving any error messages.
