An engineer must investigate the problems on a web application and address them to related teams. The engineer verifies the application reachability from the single public IP address with port and discovers that HTTPS access works to three servers of a network farm with IP 172.16.50.1 .2 and .4, but HTTPS access to the server with IP 172.16.50.3 does not work. Which problem type must be addressed as the cause for the case?
The issue described is that HTTPS access fails specifically for one server in a network farm, while it works for the others. Since HTTPS uses port 443, a blocked transport port is the most likely issue causing the connectivity problem to that particular server. If the transport port 443 is blocked for the server with IP 172.16.50.3, HTTPS traffic would not be able to reach it, even though it works for the other servers.
It's a NAT issue, right?
