  • Likely, because S1 doesn't answer to ICMP echo requests, isn't reachable on that side, or it might not have a (default) gateway. Please add the relevant device configurations to your question (using the { } function) to get a definitive answer.

  • I added S1 config file. Default gateway is missing i believe?

Your switch does not have a route to either subnet that the PCs are on.
