Hello,&nbsp;
TCP RST from remote system: &nbsp;
When a host (client or server) sends a TCP RST for an existing TCP connection, the BIG-IP system in turns sends a TCP RST to the host at the other end of the TCP connection.&nbsp;
So I suppose that your backend server (Pool Member) send a reset first.&nbsp;

You alwayse receive a reset or sometimes?&nbsp;

I have an F5 load balancing setup configured with two servers. My MVC web application, which incorporates Kendo UI, Jquery, and bootstrapping, is hosted on an IIS server with an SSL certificate. However, when accessing the application via HTTPS from outside the server, it often or sometimes results in a 'net::ERR_CONNECTION_RESET' error, with intermittent failures to load javascript and CSS files to the client browser. Strangely, upon reloading the page, the assets load properly, and the page functions as expected. This issue did not occur when the application was accessed via HTTP, where it worked properly without any issues. What could be the reason behind this problem?
