There's another link between those two switches that's forwarding and so Spanning Tree has blocked this other link to avoid a loop. LLDP (or CDP) should give you a good starting point to working out which port goes where.

there's a special circle of hell reserved for people who block ping and ICMP unreachable, along with those who shut off lldp/cdp on switches.
