I have googled many things related to this issue. I am doing signalr connection using WebSocket and longpooling, I am pinging the server every 30 sec from the connection.
When I load the first time, I don't doing anything on the page, no refresh, after some time connection is disconnected due to inactivity(he client has been inactive since 26/03/2018 30000ms and it has exceeded the inactivity timeout), and reconnected again as I have written reconnect function,
though if I calling ping method to server every 20 sec after some time server is disconnected and I don't know why.
I have enabled logging=true on client side,
my client is HTML page.
If the server is not reconnected, an error like
longpooling request is failed
occurs. On the server keepalive is null.
The first time the client is able to reconnect, but the second time not.
I don't know why the server disconnects, as I am using longpooling.
The ping method is an empty method only for the heartbeat I used.
The application is hosted using Amazon ELB.
Please help, I have tried for 3-4 days, but I could not find the issue.
