I need help with understanding why this happens. We have a server that stopped responding to calls on 443. When troubleshooting we can ping, remote, and perform other tasks. The server listens on 80. We tested with calls from with in the VLAN (we dont use intervlan ACL's) and outside the ACL. Finally we tested by changing the IP address and everythign started working. My gut says that this is a server issue with its internal firewall but the admin couldnt find any configuration blocking 443. We also tested loopback on 443 and it worked.
