i have an asp.netcore 3.1 web application that using signalr core.
i copied the app in 2 identical servers. in server #1 everything works fine in fireFox and chrome.
but server #2 app i get this error just in firefox
firefox can’t establish a connection to the server at ws://domain.com
Failed to start the transport 'WebSockets': Error: There was an error with the transport.
and after 20 seconds the connection will establish successfully in SSE.
i know that its a 'by design' error, and it seems its a common error in FF when using Sockets. but i did not found any Working Solution.
the question is why im getting this error while the server #1 is working perfectly fine? and how can i resolve this?
