Is it possible to increase the Keep-Alive timeout on an Application Gateway

Brian Brinch 61 Reputation points

We got some IoT devices connecting with an Azure App Service through an Azure Application gateway. The mobile connection has a limited data capacity each month and because of this we need the connection to be kept alive. But the connection drops after apx 50 seconds and the cost to re-open the connection or ping to keep it alive is too much.

According to this link: the default is 75 seconds in the v2 SKU. How can I increase the 75 seconds or obtain a connection that is kept alive

    The default is 75 seconds and that settings is not editable. I think your issue is caused by the Request timeout settings in the HTTP settings.


    That is editable and default is 30 seconds. Can you check and change the settings and see if that fixes your issue?
